Summary
This paper addressed the accusation that the embryological development described in the Qur'an, has been plagiarised from the writings of ancient Greek physicians, such as Galen. We reviewed the main embryological ideas found in the writings of the ancient Indians, Hippocrates, Aristotle, Galen, and Jewish scriptures, and compared these to the embryological development stated in the verses of the Qur'an.
This paper will examine the claim that the embryological development described in the Qur'an has been plagiarised from the writings of ancient Greek physicians, such as Galen. Hence, we will review what was known about embryology by the ancient Indians, Hippocrates, Aristotle, Galen, as well as the embryology found in Jewish scriptures. Then we will outline all the verses in the Qur'an, and some Hadith literature, regarding embryology and human development. In doing so it should be very obvious if there are any similarities or indeed outright plagiarism of Greek ideas which were prevalent at the time.
Ancient Indian ideas about embryology are to found in the Bhagavad Gita (2 BC) which describes structures such as the amniotic membrane. And the Susruta-samhita (2-3 AD), which says that the embryo is formed of a mixture of semen and blood (this idea was also held by the Greeks, as we shall see later), both of which originate from chyle (digested fats). The differentiation into the various parts of the body, arms and head occurs in the third month. In the fourth there follows the distinct development of thorax, abdomen and heart. Hair, nails, sinews and veins develop in the sixth month; and in the seventh month the embryo develops other things that may be necessary for it. In the eighth month a drawing of the vital force (ojas) to and from mother and embryo, which explains why the foetus is not yet viable. The hard parts body are derived from the father, the soft from the mother. Nourishment is carried on through vessels, which lead chyle from the mother
The idea of the blood being menstrual blood is interesting as it closely resembles Aristotelian doctrine. The clotting of milk into cheese analogy used by Aristotle for the formation of the embryo occurs also in Indian embryology. The Susruta-samhita compares the creamy layers (santanika) formed in milk, to semen and blood, which through chemical changes caused by heat, produce seven different layers of skin (kala). This concept occurs again in a Sutra on embryology written in Sanskrit, "Development, 0 Ananda," Buddha is made to say, "is comparable to a vessel of milk, like as this ferments and forms a kind of kefir or cheese." (A history of Embryology, J. Needham pp 25-27, Cambridge, 2nd edition 1959). Hippocrates (460 - 377 BC) was a Greek physician and founder of the Hippocratic school of medicine. The Hippocratic collection of some 60 or so medical works is ascribed to various authors and was probably not written by Hippocrates. The embryological knowledge of Hippocrates is set out in three books, the treatise on Regimen, the work on The Seed the book on The Nature of the Child (Hippocratic Writings, Penguin Classics, 1983).
Aristotle (384 - 322 BC) was a Greek philosopher and scientist who wrote over 400 books on many different branches of learning. His main embryological compendium was that entitled On the Generation of Animals. Aristotle dissected and examined many different types of animal embryos, mammalian and cold blooded. It is also possible that he dissected an aborted human embryo (Ogle, W. Aristotle on the Parts of Animals, Kegan Paul, London, 1882).
Galen (129-199 AD) was a physician and scholar, whose ideas dominated medicine until the Renaissance. Galen's theory of embryology is to be found in his On the Natural Faculties, and On the Formation of the Foetus, which deals more with the anatomical aspects.
5. Embryology in the Jewish scriptures The Talmud is one of the most important works of Jewish religious literature, which grew up between the second and sixth centuries A..D. The Talmud contains several references to embryology. The embryo is referred to as peri habbetten (fruit of the body), It grew through various definite stages:
The ideas of the Talmudic writers on the life led by the embryo in utero are well represented by the remark, "It floateth like a nutshell on the waters and moveth hither and thither at every touch".

Meanings of Qur'an and Hadith:
7. Embryo development in the Qur'an Embryo development in the Qur'an is divided in three main areas. These are as follows:
7.1 The beginning of development This is subdivided as follow:
i). Nutfah (The drop) Al-Nutfah in Arabic means a drop or a small part of fluid and Nutfah in general describes a stage where the beginnings of a human being are found in this fluid (Ref: 6A, 12/6; 17/118; 19/120: 13A, 3/436: 15A, 17/116: 1C, 2/121: 7B, 3/116: 4D, 9/235-6: 5D, 6/258: 4A, 30/234: 7A, 4/336: 10A, 13/9: 12A, 4/288). Its real meaning can only be deduced from the text of Qur'an; evidently it is a comprehensive term and includes male and female gametes and part of their natural environments of fluid. It also includes zygote, morula and blastocyst till implantation in the uterus. This is illustrated by the following citation: أَلَمْ يَكُ نُطْفَةً مِنْ مَنِيٍّ يُمْنَى "was he not a drop or part of germinal fluid (Mani) emitted or programmed" (Surah Al- Qiyama, Ayah 37)
Here "Mani" means male or female germinal fluid (Ref: 1D, 5/276: 5D, 10/348:2D, 6/2497).
The Prophet's Hadith confirms the fact that the offspring is created from part of the germinal fluids:
"Not from all the fluid is the offspring created" (Sahih. Muslim: Kitab Al-Nekah, Bab Al-Azl)
It is also known that not all parts of the ejaculate are equally potent in the fertilisation process. "In the first portion of the ejaculate are the spermatozoa, epididymal fluids, and the secretions from the Cowper and prostate gland fluids. In the last portions of the ejaculate are the secretions of the seminal vesicles. Most spermatozoa appear in the first part of the ejaculate, which is made primarily of prostatic secretions. Thus spermatozoa in the initial portion of the ejaculate have better motility and survival than those in the later portions, which are chiefly vesicular in origin".
ii) Al Maa-ad-Dafiq (Gushing, self emitting fluid) فَلْيَنظُرْ الإِنسَانُ مِمَّ خُلِقَ (5). خُلِقَ مِنْ مَاءٍ دَافِقٍ (الطارق: 6).
"Let man think from what he is created. He is created from Al Maa-ad Dafiq." (Surah, At-Tariq,86:5-6)
Linguistically, Al Maa-ad-Dafiq refers to a gushing, or self emitting fluid, or to a drop that is emitted out. In other words, it refers to a discharge that is self emitting, hence motile by itself. The use of microscope has shown that not only sperms, but the ovum also shows motility. The mature sperm is a free swimming actively motile germ cell consisting of a head and a tail. The tail provides motility to the sperm, and helps its transportation to the site of fertilisation.
Fimbrae are finger like projections which are part of the infandibulum, the funnel shaped end of the fallopian tube. The cilia, or the tiny microscopic whips on the fimbrae at the same time help the movement of the ovary to the infundibulum. Unless the sperm and ovum both exhibit movement, fertilisation cannot take place. The Qur'an term "Al Maa-ad-Dafiq" thus encompassed the gushing, the self emitting as well as the motile phenomena of this sub-stage.
iii) Sulalah Min Ma'a (Gentle extraction)
"Sulalah" in Arabic means gentle extraction from fluid (Ref: 1D, 3/56-60: 2S, 5/1730: 4D, 11/338: 5D, 7/377). Its meaning in the context used in Qur'an is clear from the following: ثُمَّ جَعَلَ نَسْلَهُ مِنْ سُلاَلَةٍ مِنْ مَاءٍ مَهِينٍ (السجدة: 8). "Then He made his progeny gently extracted "Sulalah Min Ma'a" from lowly fluid". (Surah As-Sajdah, Ayah 8)
The fluid refers to both male and female germinal fluids containing gametes and it is now a known scientific fact that both ovum and sperm are gently extracted from their environments.
The ovum is extracted in a long stream of follicular fluid. Similarly one sperm out of millions is drawn out from the seminal fluid.
Further, it is now common knowledge to embryologists that usually only one sperm and one ovum are involved in the normal process of fertilisation. This fact was stated by Prophet Mohammad in the Hadith below:
"Not from all the fluid is the offspring created". (Sahih Muslim, Kitab Al-Nekah, Bab Al-Azl)
iv) Al-Nutfah Al-Amhsaj In Arabic Amshaj means mixture and Al-Nutfah AI-Amshaj means a mixture of male and female germinal fluids or cells (Ref: 1A, 29/126-7: 2A, 2/195: 6A, 19/121: 7A, 6/418: 8A, 8/393; 9A, 2/454: 4D, 2/367). All Islamic scholars unanimously agree on deriving this meaning from the above expression. This is evidently clear from the following quotation: إِنَّا خَلَقْنَا الإِنسَانَ مِنْ نُطْفَةٍ أَمْشَاجٍ نَبْتَلِيهِ فَجَعَلْنَاهُ سَمِيعًا بَصِيرًا (الإنسان: 2). "Verily We created Man from mixture of germinal drop" (Surah Ad-Dahr, Ayah 2)
The interpretation of this Ayah to mean mixing of male and female gametes to form the Zygote. Al-Nutfah Al-Amhsaj is a peculiar combination of Nutfah, which is a noun referring to a single drop and AI-Amshaj an adjective, which is used in plural form. The grammatical rules of the language permit singular nouns or pronouns to be described by a singular adjective. Al-Amhsaj is a plural adjective used with the singular noun Al-Nutfah. After mixture of the male and female gametes, the Zygote still remains "Nutfah" and in this context the word "Al-Nutfah Al-Amhsaj" will mean a combination of many things mixed in a single drop (Nutfah) i.e., the maternal and paternal chromosomes with their genetic material and other contents of the Cell. "Amshaj" is a plural adjective capable of agreeing with the concept of Nutfah being a multi-faceted single entity.
v) Quarar Makeen (A place of settlement firmly fixed) ثُمَّ جَعَلْنَاهُ نُطْفَةً فِي قَرَارٍ مَكِينٍ (المؤمنون: 13). "Then We placed him a drop (Nutfah) in a place of settlement firmly fixed", (Surah Al-Mu 'minun, Ayah 13)
The mother's womb or uterus, which is firmly fixed in the body, for settlement of the conceptus is referred to in the Qur'an as "Quarar Makeen". There is no proper English equivalent to this expression which could give a complete concept as implied by "Quarar Makeen". This expression means settling of the conceptus in the womb and refers to the ideal situation of the latter in the mother's body for formation and growth of a new being. This phrase is comprehensive in its meanings and covers all the known facts and those which are likely to be added later because "Quarar" is comprehensive enough to cover any additional information regarding the uterus and "Makeen" could cover any future knowledge about the relationship of the uterus to the body :
vi) Three veils of darkness خَلَقَكُمْ مِنْ نَفْسٍ وَاحِدَةٍ ثُمَّ جَعَلَ مِنْهَا زَوْجَهَا وَأَنْزَلَ لَكُمْ مِنْ الأَنْعَامِ ثَمَانِيَةَ أَزْوَاجٍ يَخْلُقُكُمْ فِي بُطُونِ أُمَّهَاتِكُمْ خَلْقًا مِنْ بَعْدِ خَلْقٍ فِي ظُلُمَاتٍ ثَلاَثٍ ذَلِكُمُ اللَّهُ رَبُّكُمْ لَهُ الْمُلْكُ لاَ إِلَهَ إِلاَّ هُوَ فَأَنَّى تُصْرَفُونَ (الزمر: 6). "He created you in the wombs of your mothers from one stage to another and all along three veils of darkness surrounded you". (Surah Al-Zumar, Ayah 6)
It is known that the embryo develops within three covers which have been expressed by the Qur'an as "Three veils of darkness". These are taken to mean the following:
vii) Results of fertilization مِنْ نُطْفَةٍ خَلَقَهُ فَقَدَّرَهُ (عبس: 19). "He created (Khalaqah) him from "Nutfah" and immediately laid down the plan or programme (Qadarah) of its (future development)". (Surah 'Abasa, Ayah 19)
a. Creation Khalaqah in Arabic this means creation of a new being (Ref: 1D, 2/214: 2D, 4/1470: 3D, 157: 4D, 10/87) and aptly explains fusion of male and female gametes to form the Zygote. "this Cell marks the beginning of each of us as a unique individual". Crossing over of chromosomes by relocating segments of maternal and paternal chromosomes, serves to shuffle the genes.
b. Programming (planning) Qadarah in Arabic means "planned or programmed" and when preceded by the conjunction "FA" indicates a rapidly occurring process. In the ayah given below, "Faqadarah" is interpreted to mean that immediately upon formation of the Zygote, the future programming of the new individual is laid down. This is the result of union of male and female pronuclei, which had already undergone shuffle of genes in the process of "cross over" of chromosomes.
c Sex determination The information about sex determination is beautifully narrated in the Qur'an: وَأَنَّهُ خَلَقَ الزَّوْجَيْنِ الذَّكَرَ وَالأُنْثَى (45). مِنْ نُطْفَةٍ إِذَا تُمْنَى (النجم: 46). "And He created the two sexes male and female from a drop when ejaculated or planned (Nutfah Idha Tumna) ". (Surah An-Najm, Ayah 45, 46)
"Tumna" in Arabic means "ejaculated" or "planned". "Nutfah Idha Tumna" refers to the sperm when the meaning "ejaculation" is applied and can refer to the formation of the Zygote after the union of the sperm and the ovum, when it is taken to mean "planning" (Ref: 1A, 27/44: 2A, 4/32: 3A, 8/83: 5A, 7/117: 13A, 5/116: 19A, 7/711)
Although participation of an X and Y chromosome bearing sperms determines the sex, the new individual cannot be formed without the ovum. Here the second meaning of "Tumna" (planned or programmed) can be applied. What we know today with regards to sex determination bears out what was revealed in the Qur'an in the 7th century.
viii) The conceptus a part of a drop مِنْ نُطْفَةٍ خَلَقَهُ فَقَدَّرَهُ (عبس: 19). "He created him from (a part of) Nutfah". (Surah 'Abasa, Ayah 19)
In spite of the fact that the Nutfah Al-Amhsaj (fertilised ovum) is a small thing, yet the embryo does not develop from all its components. The inner cell mass contains the cells which later contribute to the formation of the embryonic area from which the embryo actually develops. Only a small portion of cells, derived by repeated division of the Zygote, take part in the formation of the actual embryo, Ayah 19 of Surah 'Abasa accommodates this fact: مِنْ نُطْفَةٍ خَلَقَهُ فَقَدَّرَهُ (عبس: 19). "He created him from a part of a drop (Min Nutfah) and then immediately programmed him (his future)". (Surah 'Abasa, Ayah 19)
"Min Nutfah" implies that only a small number of the total cells produced by Nutfah shall take part in formation of the embryo.
When Nutfah enlarges, part of it becomes embryonic and the greater part becomes nutritive and protective in function. These groups of cells are derived from a single "Nutfah".
This meaning is reinforced by the Hadith: "Not from all the fluid is the offspring created and if Allah willed to create a thing, nothing can make Him powerless". (Muslim: Kitab Al-Nikah, Bab Al-Azl)
ix) Nuftah Al-Ghayb Al-Ghaydh (the key of an embryo's future)
From germinal fluids to implanation اللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَى وَمَا تَغِيضُ الأَرْحَامُ وَمَا تَزْدَادُ وَكُلُّ شَيْءٍ عِنْدَهُ بِمِقْدَارٍ (الرعد: 8). "Allah knows what every female womb bears and what is penetrating into the womb or decreasing and what is increasing (Al-Ghaydh) ". (Surah Ar-Ra 'ad, Ayah 8)
And Allah's messenger (Prophet Mohammad, Allah bless him and give him peace) said:
None knows the future of what is decreasing or penetrating into the wombs except Allah". (Sahih Al- Bukhari: Kitab Al- Tafsir)
The above Surah and Hadith can be taken to consider the period of early embryogenesis from insemination to early implantation of the fertilised ovum. The key word in both the Ayah and Hadith is "Ghaydhwhich could mean:
(1) Passing through or penetration of fluid into depth, like water going into the depth of the earth (1D, 4/405: 2D, 7/202: 3D, 368: 4D, 7/405: 5D, 5/64).
(2) Decrease in amount (Ref: 1D, 4/405: 2S, 7/202: 3D, 368: 4D, 7/405: 5D, 5/64).
The above Ayah and Hadith refer to something which is passing through the female generative system, which is decreasing and or increasing in size and it is something whose future at this stage is known to no one except "Allah". This "something" evidently is a reference to the male and female generative materials and later to the zygote.
When different meanings of the key word, "Al-Ghaydh" are applied to the Ayah and Hadith above, these evidently point to the development processes taking place up to the stage of early implantation.
It is scientifically proven that of millions of sperms in the seminal fluid usually only one takes part in the process of fertilisation of the ovum, and only one ovum, out of hundreds of thousands, is extracted from the ovary. So "Al-Ghaydh" will mean a decrease in the amount of the Germinal materials used in fertilisation.
When "Al-Ghaydh" is taken to mean "passing through", it will cover the period of the journey the ovum takes to reach the uterus and during this period the ovum will be penetrated by the sperm to form the zygote.
It is clear from the above that the word "Al-Ghaydh" had been very aptly and correctly selected and we shall not be far from being correct to say that the "Al-Ghaydh" stage of development will cover from insemination to early implantation.
The above Hadith says that only "Allah" knows about the future of the conceptus in the stage of "Al-Ghaydh". It is quite evident that at an early stage of development like this, there is no way of knowing about the future of the conceptus. But scientifically, we know that soon after the zygote is formed, the future and identity of the new being has been determined and this is known to Allah only.
There are several steps in determining the identity of a new individual. At the time of ejaculation several million spermatozoa are deposited in the vagina, adjacent to the uterine cervix. This fluid contains several hundred million spermatozoa, most of which are capable of uniting with an ovum to initiate a new life. The total volume of semen is reduced by the passage of some of the spermatozoa into the cervical canal in the direction of a potential ovum. This is the first step after insemination in determining the nature of the future embryo. The female's counterpart in deciding the future embryo's nature occurs when from among the thousands of ova available in the ovaries, only one is passed into the oviduct. This is the second step of the several hundred spermatozoa reaching the ovum only one will penetrate the female gamete's cytoplasmic membrane and this is a third step in deciding the nature of the future person and it too is covered by the stage of Ghaydh. As a result of fertilisation the dominant and recessive genes possessed by the parental chromosomes establish the new individual's genetic potential.
Through all of these reproductive and development events the future expression of inherited potential is largely decided and though they themselves are generally not directly observable, their effects will become evident to all, later in life. The Hadith says that the key to the embryo's future is decided, at Ghaydh.
According to the Hadith, the keys of the unknown are five which no one knows but Allah, and one of these unknowns is the future of the stage of "Al-Ghaydh".
"The keys of the unknown are five, no one knows them but Allah; no one knows what is in the future except Allah, and no one knows the future of what in the wombs are decreasing or what penetrating into them, except Allah". (Sahib AI-Bukhari: Kitab Al- Taf'ir)
From the above ayah it is understood that the relationship of the conceptus with the uterus is in two stages: Al-Ghaydh and Izdiad Al-Rahem, the preamble of the above Hadith tells us that the key to the future of the conceptus is decided at Al-Ghaydh and that no one but Allah knows it. The stage of Al-Ghaydh can be taken to include "Al-Harth" or implantation.
x) Al-Harth (implantation)
It is stated in the Qur'an: نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ وَقَدِّمُوا ِلأَنفُسِكُمْ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّكُمْ مُلاَقُوهُ وَبَشِّرْ الْمُؤْمِنِينَ (البقرة: 223). "Your wives are as a tilth unto you; so approach your tilth when or how you will". (Surah Al-Baqarah, Ayah 223)
In the above Ayah is a description which is borne out by present day knowledge of the passage of Nutfah. Its entrance in the mother's genital tract during coitus is similar to the process of ploughing and planting.
The entry of the sperms into the uterus is similar to the planting of seeds in the land. The entry of the sperm into the ovum also carries meanings similar to ploughing and planting. And finally the implantation of the fertilised ovum (Nutfah-Amshaj) is also similar to the planting of a seed.
Harth is one word which had conveyed to Islamic scholars centuries ago the meaning and wisdom they had understood (4D, 2/134: 5D, 1/614: 1A, 2/231: 2A, 1/91: 7A, 1/335: 19A, 1/124). These meanings have also been confirmed by modern science in minute detail which the ancient scholars could not understand
7.2 The second phase of embryo development
This is subdivided as follows
i) The 'Alaqah stage ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ (المؤمنون: 14). "Then (thumm) We made the drop into an 'Alaqah". (Surah Al-Mu 'minun, Ayah 14)
In Arabic the word ‘Alaqah in fact has several meanings;
Amazingly each of these terms can be applied to the developing embryo with stunning precision. All of these terms encompassed by the word ‘Alaqah describe the appearance of the embryo as well as its relationship with the womb. From the discussion below it becomes clear that the embryo resembles a primitive multicellular organism which is attached to a host and feeding on its blood.
a) something which clings
Modern science informs us that once the egg has been fertilised in the Fallopian tube it undergoes successive divisions to form a ball like structure of 12-16 cells by the third day. This structure is called a blastocyst and it reaches the uterus in 4 to 5 days. The blastocyst then lies free in the uterine secretions for a further 2 days. About a week after fertilisation the blastocyst begins to attach and implant into the uterine wall. By the 11th to 12th day it is completely embedded in the uterine wall. At this stage chorionic villosities begin to develop like roots in the soil, these draw nourishment from the uterus necessary for the blastocyst's growth. These formations cover the whole blastocyst and make it literally cling to the uterus. By the end of the second week implantation is complete. Inside the blastocyst the embryo is anchored to the wall of the chorionic cavity by a connecting stalk. Hence, these different ways of clinging and attachment seem to represent the most dominant features from day 7 to 21, and are perfectly described in the Qur'anic description by the word ‘Alaqah. For greater detail see S. Hussain (1986) ‘Al-‘Alaq:the mystery explored, Ark Journal, London, pp. 31-36.
b) a suspended thing
The 3 week old embryo inside the blastocyst which is embedded in the uterine wall is seen to be suspended in the chorionic cavity by means of the connecting stalk and is surrounded by the amniotic cavity and the yolk sac. Therefore, the term ‘Alaqah accurately describes the suspended embryo after it has been implanted.
c) a leech-like structure
The word ‘Alaqah can also be translated as ‘leech like structure'. The leech is a elongated pear shaped creature which thrives on blood sucking. At this stage of development the embryo from top view does bear a resemblance to a leech. This resemblance is even more marked if the 24 day old embryo is seen from the side. It is also interesting to note that the embryo is now dependent on the maternal blood for its nutrition and behaves very much like a leech!. (For greater detail see Moore, KL. ‘A scientists interpretation of references to embryology in the Qur'an.' Journal of the Islamic Medical Association of US and Canada, 1986, 18:15, and Moore, KL. and Azzindani, AMA.: "The Developing Human, Clinically Orientated Embryology, With Islamic Additions". 3rd Ed., Dar Al-Qiblah and WB Saunders).
In conclusion, whichever of the above terms are used to translate the word ‘Alaqah they are all stunningly accurate descriptions of the embryo at this stage in it's development as confirmed by modern science.
There is a gap of a few days between the stages of implantation (Nutfah) and 'Alaqah and this period is clearly explained by the above Ayah:
The word "Thumm" in Arabic is a conjunction indicating a time lag and the Ayah will, therefore, mean that after some time we created the "Nutfah" into 'Alaqah.
ii) Al-Mudghah
External appearance
The Qur'an describes the embryo as evolving into a Mudghah, which means something which has been chewed (especially a piece of meat) or which has the appearance of having been chewed (Ref: 1D, 5/330: 5D, 6/430: 2D, 4/1326). This seemingly crude description is in fact quite accurate: after the fertilised egg lodges itself in the uterus, it begins to receive its first nutrients and energy from its mother. Consequently, it begins to grow especially rapidly, and after a week or two it looks like a ragged piece of meat to the naked eye. This effect is enhanced by the development of small buds and protrusions, which will eventually grow into complete organs and limbs.
At 28 days old the embryo is in the Mudghah stage. The irregular surface showing somites, resembling teeth prints on a substance, which has been chewed The external appearance of this stage of embryonic development is, therefore, described as something which has no particular fixed features. It is characterised by irregularities on the surface with depressions and bulges. The only fixed feature in a "Mudghah" is the mark of a set of teeth. It is suggested that the row of somites which is characteristic of the embryo when it starts to show features of rapid shaping may be likened to the marks of the teeth.
This quick change is described in the Qur'an by using the conjunction "FA" which in Arabic indicates a quick sequence of events. ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ (المؤمنون: 14). "Then (fa) we change (khalaq) the leech-like structure into a chewed-like substance (Mudghah)". (Surah Al-Mu 'minun, Ayah 14)
This transformation is very rapid, so the Qur'an describes this by using the word (fa) denoting a quick rather than a delayed change. According to linguistic references, the word Mudghah has several meanings. The first meaning is "something chewed by teeth". A second meaning is "a small substance". A third meaning is "a small piece of meal like a morsel". Abdullah Yusuf Ali in his commentary of the Holy Qur'an translated Mudghah as "morsel of flesh"; whereas, Mohammed Asad, Maurice Buccaille and others have chosen a better translation i.e. " a chewed like lump".
Recent studies in embryology have testified the appropriateness of the term Mudghah for describing the embryonic changes at this stage.
Since the embryo receives its nourishment from the uterus, it goes through a rapid process of growth, as described by the Qur'an term fa. Its cells assume a bead like structure and appear like a substance that has teeth imprints. The embryo later turns its position due to changes in its centre of gravity. This is similar to the turning of a morsel during the act of chewing. All of these changes perfectly corroborate the first meaning of Mudghah.
The embryo at this stage is very small, approximately (1.00) cm in length. it should be noted that the preceding stage of Alaqah is not equal to the size of a morsel, since it is no more than 3.5 mm in length. This corresponds to the second meaning of Mudghah, in terms of being a small substance. The third meaning of Mudghah,. i.e., as a piece of meal like a morsel, applies again to the size and shape of the embryo at this stage. Hence the Qur'an term Mudghah is a more precise and comprehensive description of this stage than the term somite which is used by the embryologists. It accurately describes the external form of embryo as well as its stages of internal development. One should recall that these details were not known to mankind even a few years back.
ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ (المؤمنون: 14). "Then of that leech-like structure we made a chewed-like substance, then we made out of that chewed-like substances a skeleton (bones)" (Surah Al-Mu 'minun, Ayah 14)
The above Ayah, tells us that the embryo at the stage of Mudghah does not have flesh in it, because the flesh is stated to come after the bones stage. The other interpretation ofMudghah as a piece of meat the size of a bite is most likely meant to refer to the shape rather than its size as the Qur'an tends to describe the external appearance of the embryo (only Allah knows best).
At the stage of the "Mudghah" other texts use the verbs "Khalaq" (creation, formation, initiation). This means that there is an active process of development. Throughout the embryo there is active differentiation in almost every system.
The Qur'an also describes the Mudghah to be consisting of differentiated and undifferented components.
ثُمَّ مِنْ مُضْغَةٍ مُخَلَّقَةٍ وَغَيْرِ مُخَلَّقَةٍ
"Then out of a chewed-like substance partly differentiated and partly undifferentiated (Mokhalaqa wa Ghair Mokhalaqa) ". (Surah AI-Haj, Ayah 5)
This superb Qur'anic Ayah for an embryo of about 1 cm. gives a description of its internal state by explaining that although the anlage of all organ systems have formed, their function has yet to appear. This is very meaningful in the sense that although there is creation of systems going on, this process is incomplete and the whole thing is just a lump of irregularly shaped tissue chewed-like substance
Thus the Qur'an has given a clear sequence of development by describing the changes of 'Alaqah to Mudghah and Mudghah to Skeleton. This sequence is supported by present day Embryology.
iii) Jam'a Al-Khalq (Compilation - the first forty days)
In an embryo of 40 days which is about 1 cm. long all the main organ systems have their anlage gathered together as mentioned in the Hadith.
"In every one of you all components of your creation are gathered together by 40 days and in that it is an "'Alaqah" like that, then in that it is a "Mudghah" like that". (Muslim: Kitab Al-Qadar and Bukhari, but without the words "in that)
Jam'a Al-Khalq is a comprehensive word and covers the following:
All the above events happen in the first 40 days.
According to this Hadith when organs and systems have developed during the first 40 days period, the embryo has also passed through the complete "Alaqah" and "Mudghah" stages during the same period.
The above Hadith, however, had been interpreted to mean that each of the stages took 40 days in Sequence. And some have used this to attack the whole concept of embryo development in the Qur'an. However, these people overlook the fact that there is another Hadith which explicitly states that the stage of creation of the specific differentiated organs start after the first 42 days.
"When forty-two nights have passed over the "drops" Allah sends an angel to it' who shapes it and makes its ears, eyes, skin, flesh and bones. Then he says, 0! Lord, is it male or female? and your Lord decides and the angel records it". (Muslim: Kitab Al- Qadar)
This Hadith indicates that the Nutfah, 'Alaqah and Mudghah stages are completed before 42 days. Further, the bones stage which follows the Mudghah (Ayah 14, Al-Mu'minun) is now stated to occur after 42 days according to this Hadith. If the interpretation of the first Hadith is correct this will mean that the bones appear after 120 days. The Hadith used the phrase "like that" which can be interpreted as a repetition of the time period or as a repetition of the completion of form in each of the stages of 'Alaqah and Mudghah. Thus the phrase is "Mujmal" general; but in the second Hadith it is explicitly (Mubayyan) stated that the bones start to differentiate after 42 days. The rule followed by Muslim scholars Interprets the "Mujmal" in the light of "Mubayyan" which clarifies the generalisation and gives the specific meaning and intention of the speaker.
As early as 651 A.H. Ibn Azzamlakani had reached the conclusion that the stages of 'Alaqah and Mudghah were completed during the first forty days:
Ibn Azzamlakani states: "Then he becomes 'Alaqah like that" meaning that in the 40 days mentioned the conceptus will be 'Alaqah which is completely and perfectly formed within the perfection which is possible for it. Thus they are equal in completion in its generality and not in particularities. "Then he becomes Mudghah like that" i.e. in its own share of the 40days also completely formed as the complete human being is perfectly formed. In Arabic usage, it can be said that a man changes during his life and this can be explained by saying: then be becomes an infant, then he is weaned, then he is a child, then he is a youth, then he becomes middle aged, then he becomes an old man, then HE, ALLAH, decides that he dies after that".
iv) Izam (bones stage)
The seventh week
The Qur'an uses specific terms to describe different stages. It is observed that the shape of the embryo determines the selection of the term used for each stage, e.g. the Nutfah changes to 'Alaqah when it loses its drop-like appearance. Similarly the 'Alaqah changes to Mudghah according to the change in shape.
It is mentioned in the Qur'an:
فَخَلَقْنَا الْمُضْغَةَ عِظَامًا "Then we made out of that chewed-like substance bones" (Surah Al-Mu 'minun, Ayah 14)
Accordingly the stage which follows the Mudghah stage will be called the bones (Izam) stage for the same reason.
The anlage of the skeleton which formed in the embryo during the "Mudghah stage" (between 25-40 days) transforms into cartilaginous models indicating the shape of future bones. Thus, the shape of the embryo changes from ''Mudghah shape" to one determined by the form of the skeleton. The embryo is now in the Bones (Izam) stage.
In the bones stage, various organs take up new positions in relation to the growth of the skeleton. This stage is of special significance in that it gives the embryo human features.
v) The formation of bones
"When 42 nights have passed over the Nutfah, Allah sends an angel to it, who shapes it and makes its ears, eyes, skin, flesh and ~ (Sahih Muslim: Kitab Al- Qadar)
The reason for calling it the bones stage is that at this time spreading of the skeleton starts, giving the body its human shape. This skeleton, however, is made of a soft substance at this stage (cartilage) which eventually changes to another creation during the stage of Al-Nash'ah.
The Qur'an also points out the nature of this advancement in the developmental process (change in the creation) of the embryo which becomes another creation physically and spiritually.
"In every one of you all components of your creation are gathered together by 40 days and in that it is an "'Alaqah" like that, then in that it is a "Mudghah" like that". (Muslim:Kitab Al- Qadar and Bukhari, but without the word "in that")
According to this Hadith the bones are among the parts of the creation which are gathered together during the first 40 days. According to the modern embryological descriptions all the systems of the body are represented by primordia during the first 6 weeks when the embryo is 1 cm long. These organs, however, do not have the forms we are familiar with. This is also true of the bones at this stage. They are being formed but have not yet taken the shapes and forms of the bones we know.
فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً "And then we changed the leech-like structure into a Mudghah (chewed-like substance) then we made out of that Mudghah bones (skeleton)". (Surab Al-Mu 'minun, Ayah 14)
This Ayah tells us that the bones follow the Mudghah stage. As explained above the Mudghah stage ends by about 40 days. Thus the bones stage comes after the first 40 days.
vi) Al-Kisa'a Bil-Lahm (clothing with flesh stage of, muscles)
فَكَسَوْنَا الْعِظَامَ لَحْمًا "Then We clothed the bones with flesh" (Surah Al-Mu 'minun, Ayah 14)
The above Ayah explicitly states that the bones are formed first and that this is followed by the formation of flesh or muscles which take their position around the bones (clothing the bones). In fact the primordia or precursors of both the bone and muscle (in the form of myotomes and selertomes( are present together with those of bones and other tissues and organs in a collective primitive structure are formed during the first 40 days and is found in the Mudghah. However, in this stage the primordia of muscle have not yet differentiated into definitive bones and muscles. As they do not have the shapes or forms of bones or muscles, the whole embryo at this stage does not have a human appearance.
During the seventh week- the skeleton begins to spread throughout the body and the bones take their familiar shapes. The embryo then starts to acquire the human appearance. At the end of the seventh week and during the eighth week the muscles take their positions around the bone forms, "definitive muscles of trunk, limbs and head are well represented and foetus is capable of some movement".
With the completion of this stage "Alkisa'a Billahm" at the end of the eighth week the embryo becomes a foetus and thus the stage of Nash'ah begins as stated by the remainder of the above Ayah.
فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ "Then We clothed the bones with flesh; then We developed out of him another creature. So blessed be Allah, the best to create". (Surah Al-Mu 'minun, Ayah 14)
The Qur'anic Ayah tells us that: clothing with flesh follows upon the bones stage. It has been explained previously that the terms used to describe various stages of development are derived from the feature which dominates and determines the shape of the embryo or foetus during that stage e.g. the shape of the skeleton determines the general appearance of the embryo in the bones stage during the 7th week; muscles do not develop at the same time but their development follows soon after. The muscles take their positions around the bones throughout the body and therefore Clothe the bones. Thus, the muscles take their well known forms and structures. This is referred to in the Qur'an:
فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا "Then We made of that Mudghah bones (skeleton) then We clothed the bones with flesh (muscles)..." (Surah Al-Mu 'minun, Ayah 14)
At the "Clothing with Muscles Stage" the embryo acquires human features and starts to become more straight. The external genital organs start to become differentiated.
The Qur'an has placed the stage of clothing with muscle to mark the end of embryonic stage; the foetal stage (Nash'ah) follows, as explained in the Ayah:
فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ (المؤمنون: 14). "Then We made of that Mudghah bones (skeleton) then We clotted the bones with flesh (muscles) then We developed out of him another creation, so blessed be Allah the best to create". (Surah Al-Mu-minun, Ayah 14)
The stage of clothing with muscle occurs during the 8th week which is the end of the embryonic stage after which it goes to another stage with other features, the foetal stage or "AI-Nash'ah".
vii) After the 42nd day
The developmental events after 42 days are described in the Hadith:
"When forty two nights have passed over the Nutfah, Allah sends an angel to it, who shapes it and makes its ears, eyes, skin, flesh and bones. Then he says "0 Lord! Is it male or female?" And your Lord decides what He wishes and then the angel records it". (Muslim: Kitab Al- Qadar)
By the beginning of the seventh week of development the embryo has acquired a skeleton, mostly cartilaginous, which gives form to the body of the embryo and recognisable human characteristics. After the 42nd day, the limb buds are longer with differentiated fingers and toes. The tail bud; which was previously conspicuous, has regressed almost completely.
The eyes migrate from the sides to their definitive position and the primordia of the face merge to confer human features. The anlage of the eye and ears make their appearance before the seventh week, but they do not have a human appearance as yet. After the 24th week, the foetus can hear sound, and by the 28th week, the retina becomes sensitive to light. External, middle and internal parts of the ear are formed after the 42nd day and then acquire its function and recognisable human shape.
The skeletal system, muscles and skin are fully developed and with recognisable human characteristics after the 42nd day. The skin is differentiated into epidermis and hypodermis, more characteristic of the adult by 12 weeks.
During the 4th week the anlage of the external genitalia appear and not until the 9th week do they start to show any distinguishing sexual characteristics. The male foetus can be clearly distinguished from the female only by the 12th week.
According to the Hadith, while all other organs and systems are well formed and have acquired human characters, the morphological appearance of the external genitalia (by which sex can be identified with the naked eye) is not distinct enough to permit sexual identification. The Angel asking about the sex is a reference to this fact.
7.3 The foetal period
i) Al-Nash'ah (another development)
ثُمَّ جَعَلْنَاهُ نُطْفَةً فِي قَرَارٍ مَكِينٍ (13). ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ (المؤمنون: 14). "We then placed him as a drop (Nutfah) in a place of settlement firmly fixed". Then We made the drop into an 'Alaqah (leech-like). And then We changed the leech-like structure into a Mudghah (chewed-like structure), then We made out of that Mudghah bones (skeleton, Izam). Then We clothed the bones with flesh (muscles, Lahm). Then We developed (ansha'a) out of him another creation." (Surah Al-Mu 'minun, Ayah 13-14)
At the end of the 8th week clothing with muscle occurs (AI-Kisa Bil-Lahm) and before the 12th week there is a period of slow growth and development. By the twelfth week there are important developments as well as the beginning of notable changes in the size of the foetus.. The most obvious difference with the embryonic period is that the foetus has acquired definite signs of human appearance
The verb "ansha'a" carries two meanings (a) to initiate and (b) to cause to develop (1D, 5/428: 2D, 1/77: 4D, 1/170: 5D, 1/126); both of these meanings apply to the foetal period.
New developments pertaining to the first of these meanings are given by the following extract from Persuad and Azzindani (1983):
"At twelve weeks gestation, centres of ossification are present in most bones. The limbs are differentiating and nails can be detected on the fingers and toes. Lanugo hair is present on the skin, which is now fully differentiated into epidermis and hypodermis. The testes have begun their descent and the internal genitalia (uterus, fallopian tubes, vagina) are developing. At this stage, a male foetus can be distinguished from a female on the basis of the external genital organs. Voluntary and smooth musculature are established. Foetuses at this stage of development reveal spontaneous movements, and reflex muscular contractions can be elicited by an external stimulus".
Other developments, pertaining to the second meaning, are the general growth of body and various organs in size as well as the structural nature of the tissues. The distinction of the external genitalia by inspection can also be made at about the 12 th week.
Many Muslim scholars believe that soon after the embryonic period which ends by the clothing of bones with flesh, the 'soul' comes into the conceptus.
ii) Period of Nash'ah
Let us consider the following Ayah:
الَّذِي خَلَقَكَ فَسَوَّاكَ فَعَدَلَكَ (7). فِي أَيِّ صُورَةٍ مَا شَاءَ رَكَّبَكَ (الإنفطار: 8). "Who (Allah) created you, made you even and straight (Sawwak) and then modified (Addalak) you. in whatever form (facial features) He wanted. He put you together". (Surah AI-Infitar, Ayah 7,8)
"Sawwak" means to make even and straight (2A, 4/228: 4A, 31/80: 2B, 2/666: 1C, 3/79: 1D, 3/113: 2D, 6/2384-6: 4D, 14/408: 5D, 10/189) The pluripotent cells of the embryo begin to follow various lines of differentiation and modify into different functional moieties. This process is essential for straightening and the formation of organs essential for viability. Also at this stage body surface is becoming more even and its configuration is straighter
"Addalak" in Arabic has many meanings; but in this context it means modifying in form and shape to create a definitive thing. Changes can be taken to indicate the concept of the word "Addalak" as used in The Qur'an (1D, 4/246-7: 5D, 8/209).
"Fa' Addalak" as stated above shall be taken to mean "then immediately modified your form" since "'Addalak" is qualifying the latter part of the Ayah which means that Allah constructed you in any shape He liked, this is done, of course by modifications.
A group of Muslim scholars interpreted this Ayah by considering that "Addalak" is linguistically placed to explain what comes after it i.e., the acquisition of human features.
iii) Al-Qabliyah lil Hayah (viability)
There is no sharp limit beyond which survival of the foetus is assured but experience has shown that a foetus whose fertilisation age is less than 22 weeks, rarely survives. Considering the two "Ayah" below, this can be taken to mean that the foetus becomes viable at about 6 months.
وَحَمْلُهُ وَفِصَالُهُ ثَلاَثُونَ شَهْرًا The duration of pregnancy and separation is thirty months. (Surah Al-Ahqaf, Ayah 15)
وَفِصَالُهُ فِي عَامَيْنِ "His separation is at the end of two years". (Surah Luqman, Ayah 14)
Thus the total period of breastfeeding plus the period of pregnancy is stated as thirty months. It is also stated that for two years the child is fed on the mother's breast at the end of which he is weaned. The two texts taken together leave only 6 months (22 weeks i.e., five and half Gregorian months are equal to about six lunar months. of pregnancy). This is about the same period, which has been established for viability.
This interpretation was derived by Ali Ibn Ali Talib (may Allah be pleased with him) from the above two Ayahs and another Ayah:
وَالْوَالِدَاتُ يُرْضِعْنَ أَوْلاَدَهُنَّ حَوْلَيْنِ كَامِلَيْنِ لِمَنْ أَرَادَ أَنْ يُتِمَّ الرَّضَاعَةَ "Mothers shall breast feed their offspring for two whole years, for those who want to complete the breast feeding". (Surah Al-Baqarah, Ayah 233)
This interpretation was also agreed to by Khalifa Othman (may Allah be pleased with him) and a group of the Prophet's companions.
iv) Al-Hadanah Al-Rahemiah (Uterine support)
وَحَمْلُهُ وَفِصَالُهُ ثَلاَثُونَ شَهْرًا "The duration of pregnancy and separation is thirty months" (Surah Al-Ah qaf Ayah 15)
وَفِصَالُهُ فِي عَامَيْنِ "His separation is at the end of two years (Surah Luqman, Ayah 14).
From the comparison of the two "Ayah" we learn that the duration of pregnancy is 6 months, but it is a common knowledge that the duration of pregnancy is 9 months. How then do we account for the shortage of 3 months in the account given by the Qur'an?
The explanation is that the real period of pregnancy is 6 months, during which the foetus is essentially dependent on his mother for its survival. However, if born immature at the end of a minimum of 6 months of pregnancy, the child can survive outside the body of the mother with outside support. Thus the last 3 months not accounted for, in fact correspond to this period of possible survival outside the mother's body.
iv) Izdiad Al-Rahem (Increase in size of the uterus)
اللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَى وَمَا تَغِيضُ الأَرْحَامُ وَمَا تَزْدَادُ "Allah knows what every female bears and what is penetrating and decreasing in the womb and what is increasing" (Surah Al-Ra'd, Ayah 8)
When Al-Ghaydh stage of the Nutfah (which may be taken to include the process of implantation) is completed the embryo establishes contact with the mother's circulation and thus receives the required amounts of nutrients, which are necessary for its development. A rapid stage of development follows and the size of the uterus then begins to increase (Izdiad Al-Rahem).
If we refer to the stage of AI-Ghaydh we note that the key to the embryo's future is decided at this stage and no one knows this but Allah. One of these aspects is the sex of the embryo.
We understand from the interpretation of Al-Bukhari of Surah Al-ra'd that the key to the future of the embryo lies in the stage of AI-Ghaydh. On the other hand the following Ayah informs us that the conceptus passes through two stages:
a) The stage of AI-Ghaydh: This includes the key to the future according to Al-Bukhari an (told by Abdullah Ibn Omar, may Allah be pleased with both). and also no one knows what is in the wombs, of what Allah wants to create, except Allah, Glory be to Him; but if Allah willed it to be male or female, unhappy or happy, He informed the Angels who are concerned with that and those He wished to inform of His creatures".
b) The stage of Izdiad: This is outside the aspects, which are part of the key to the embryo's future, as concluded from the above Ayah. Therefore, Izdiad Al-Rahem is a stage open to human knowledge as it lies outside the keys to the future, which only Allah knows.
The Hadith tells us on many occasions that Angels after the first 40 days know many things about the embryo's future e.g. sex, happiness etc. This can be taken to indicate that it is also possible for man and others to know something about the embryo's future. This is possible in the stage of Izdiad Al-Rahem which, as explained above, lies outside the keys of the future which only Allah knows. This conclusion was drawn by Ibn Kathir (vol. 3, pp 454-6).
v) Tayseer Assabil (making the passage easy)
"Parturition, or labour"
ثُمَّ السَّبِيلَ يَسَّرَهُ (عبس: 20). "Then we made the passage (through the birth canal) easy". (Surah 'Abasa, Ayah 20)
Birth is a dangerous time for many women and the birth canal appears to be a difficult passage for the baby. Normally the vagina can only admit 3-4 fingers, while the cervix uteri is so tightly closed that even the little finger cannot be admitted into it. These tight passages are surrounded by a rigid ring of bony pelvis.
"Allah" says that He made the passage (through the birth canal) easy. We now know on the basis of the following scientific discoveries as to how this passage is opened up to allow birth to take place. This is what the Qur'an is referring to by using the general tern "easy".
a) Relaxing: A hormone secreted by the ovaries and placenta, loosens the ligaments of the pelvic joints, and softens the cervix.
b) Bag of Water: With each uterine contraction the membranes filled with amniotic fluid bulge as a bag of water through the cervix uteri and facilitate its dilatation. After rupture of the water, the membranes provide a smooth slippery surface for the foetus to glide down.
c) Mechanism of Labour: A series of changes in the attitude and position of the foetus facilitate its passage through the irregularly shaped pelvic cavity. As an example these changes for the occiput position are descent, flexion, internal rotation, extension, restitution and external rotation.
All the above mentioned factors contribute in various ways to make the passage of the foetus through the birth canal easy.
7.4. Miscellaneous topics
i) Dominant and recessive characters in the light of the hadith
It is well known that inherited characteristics can be dominant and therefore appear in the offspring immediately, but may be recessive and therefore can remain dormant and appear in future generations.
We shall consider two texts from The Hadith. The first of these is concerned with dominant characteristics and the other with recessive characteristics.
a) Dominant characteristics
"0, Allah make us enjoy our hearing, our vision and our strengths as long as you make us live and make that our inheritor". (AI-Tirmidhi and Al-Hakim in Al-mustadrak)
The use of the word "inheritor" rather than inherited is meaningful. It is obvious that the characteristics are inherited. In the above Hadith it is placed grammatically as a subject rather than an object. It is impossible for the characteristics to inherit us during our life time (as understood by some Muslim scholars). The first part of the Hadith teaches us to request from Allah that we enjoy them during the whole of our life time. Further more, heredity by definition occurs between parents and offspring.
This understanding by some Muslim scholars was due to the fact that "inheritor" is never used to describe what is inherited by children from parents in which case the word "inherited" is used. The deviation from this rule in the Hadith by using "inheritor" (Al-Warith) must have a special meaning.
The answer to this lies in recent discoveries on the role of dominant genes, which exert a controlling influence in heredity and therefore cause the recessive genetic characteristics not to appear in the offspring.
Thus the request for inheritance of the characteristics mentioned in the Hadith is in the subject form (Al-Warith) i.e. dominant rather than the object i.e. passive or recessive.
b) Recessive characteristics
Abu-Huraira narrated: A man came to the Prophet Mohammad (Salla Allah Ta'alah 'Alaihi Wa Salam), and said:
"0 Allah's prophet, A black child has been born for me"! The Prophet asked him, "Have you got camels?" The man said, "Yes". The Prophet asked him, "What colour are they?" The man replied, "Red". The Prophet said, " Is there a grey one among them?" The man replied, "Yes". The Prophet said, "Whence comes that?" He said, "May be it (colour) was pulled out by a hidden trail". The Prophet said, "May be your son's (colour) was also pulled out (by a trait)" (Al- Bukhari: Kitab At- Talaq, Bab Idha Arrada Benafi Al- Walad, (by a trait) in the answer of the Prophet was included in Bakhari, Kitab al-Hudood)
The first Hadith dealt with dominant characteristics and this one deals with Recessive genetic characteristics. It must be remembered that this was revealed to the Prophet some one thousand and four hundred years ago.
Two conclusions can be drawn from this Hadith. First, the deduction by the Prophet of similarity of heredity laws in man with those in animals. Second, that a characteristic which becomes hidden (recessive) for several generations may appear again in the future. This is in complete agreement with the present knowledge of the laws of heredity.
In summary this incident tells us that the Prophet (Salla Allah Ta'alah 'Alaihi Wa Salam) has clarified to the man an aspect of heredity which was unknown to him. This was achieved by inducing the conclusion from the man's own environment which was welt understood by him. The Prophet then accepted his conclusions.
ii) The critical period
When forty-two nights have passed over the conceptus, Allah sends an angel to it, who shapes it shapes it, makes its ears, eyes, skin, flesh and bones. Then he says 0 Lord! is it male or female ? And your Lord decides what He wishes and then the angel records it". (Muslim - Kitab Al- Qadar)
This is a remarkable Hadith which gives a wonderful description about the period of conception when different organs and tissues are taking shape on account of various chemicals like: inducers, organisers, hormones, enzymes, etc. This is about the same time when the Hadith says that an angel comes and begins to model a new being. The remarkable point about the Hadith is that it precisely records the time when these organs are differentiating and can be influenced by external factors.
iii) Gross congenital deformities
We do not see many deformed babies in real life. The majority of grossly malformed embryos and foetuses never come to term. Even if they are born and survive they can not reproduce. It is stated in the Hadith:
"Allah never gives offspring to a monster nor does He give him grandchildren". (Sahih Muslim: Kitab Al- Qadar)
The genetic sex established at fertilisation does not always result in clear-cut male or female appearance of the external genitalia. Errors in sex development occur about once in every 1000 foetuses which result in various degrees of intermediate sex, a condition known as inter-sexuality. These sexually abnormal individuals cannot reproduce because their reproductive organs have not developed normally and as a result they are non-functional.
The word "monster" in the translation is used to indicate the condition in which the child is grossly malformed due to congenital abnormalities. Gross malformations usually affect the central nervous system and the endocrine system both of which are essential for normal reproduction.
It can also be concluded from the Hadith that this general statement applies to animals as well as man, because it was made on an occasion when an animal was mentioned.
Congenital deformities can also result from infective agents: sexual promiscuity has long been associated with syphilis and gonorrhoea. Because of sexual permissiveness, there is an alarming increase of relatively new and more severe venereal infections for which there is no cure at the present time. These include genital herpes and Acquired Immune deficiency Syndrome (AIDS) which are gradually reaching epidemic proportions. It is appropriate to quote the Hadith on this topic:
"Whenever sexual permissiveness spreads among the people until it becomes declared, infections and killing disease as well as illnesses not previously found in their ancestors will also spread among them (Related by Ibn Majah, AI-Bazzar and Al- flaihaqi) | |
