It is We Who have created you. Why, then, do you not accept the truth? Have you ever considered that [seed] which you emit? Is it you who create it? Or are We the Creator? (Qur'an, 56:57-59)
The fact that man is made not from the entire semen—but only a small part of it—is related in the Qur'an with the expression, "a drop of ejected semen."
Sperm undertake a journey into the mother's body until they reach the ovum. Only a thousand out of 250 million sperm succeed in reaching the ovum. At the end of this five-minute race, the ovum, half the size of a grain of salt, will let only one of the sperms in. That is, the substance of man is not the whole semen, but only a small part of it. This is explained in the Surat al-Qiyama as follows:
Does man reckon he will be left uncontrolled [without purpose]? Was he not once a drop of ejected semen? (Qur'an, 75:36-37)
As we have seen, the Qur'an informs us that man is made not from the entire semen, but only a small part of it. That the particular emphasis in this verse announces a fact only discovered by modern science is evidence that the Qur'an is the Word of Allah.
The Mixture in the Semen
In the Qur'an, it is said that masculinity or femininity are created out of "a drop of semen which has been ejected." Until fairly recently, it was believed that a baby's sex was determined by the mother's cells. Science only discovered this information given in the Qur'an in the 20th century. This and many other similar details about the creation of man were stated in the Qur'an centuries ago.
The fluid referred to as semen, which contains the sperm, does not consist of sperm alone. On the contrary, it is made up of a mixture of different fluids. Seminal fluid is a collection of substances secreted from the testicles, the seminal vesicles, the prostate gland and glands linked to the urinary tract. A detailed analysis of this fluid shows that it consists of a great many separate substances, such as citric acid, prostaglandin, flavin, ascorbic acid, ergothioneine, cholesterol, phospholipids, fibrinolysin, zinc, phosphatase acid, phosphase, hyaluronidase and sperm. These fluids exercise different functions, such as containing the sugar necessary for providing energy for the sperm, neutralizing the acids at the entrance of the uterus, and providing a slippery substance for the easy movement of the sperm.
When semen is mentioned in the Qur'an, this fact, which was discovered by modern science, is also referred to, and semen is defined as a mixed fluid:
We created man from a mingled drop to test him, and We made him hearing and seeing. (Qur'an, 76:2)
In other verses, semen is again referred to as a mixture, and it is stressed that man is created from the "extract" of this mixture:
He Who has created all things in the best possible way. He commenced the creation of man from clay; then He made his progeny from an extract of discarded fluid. (Qur'an, 32:7-8)
The Arabic word "sulala," translated as "extract," means the essential or best part of something. By either meaning, it refers to "part of a whole." This shows that the Qur'an is the Word of Allah, Who knows the creation of man to its minute details.
The Sex of the Child
Until fairly recently, it was thought that a baby's sex was determined by the mother's cells. Or at least, it was believed that the sex was determined by the male and female cells together. But, we are given different information in the Qur'an, where it is stated that masculinity or femininity is created out of "a drop of sperm which has been ejected."
He has created both sexes, male and female from a drop of semen which has been ejected. (Qur'an, 53:45-46)
Was he not a drop of ejaculated sperm, then a blood-clot which He created and shaped, making from it both sexes, male and female? (Qur'an, 75:37-39)
The developing disciplines of genetics and molecular biology have scientifically validated the accuracy of this information given by the Qur'an. It is now understood that sex is determined by the sperm cells from the male, and that the female has no role in this process.
The Y chromosome carries characteristics of masculinity, while the X chromosome carries those of femininity. In the mother's egg, there is only the X chromosome, which determines female characteristics. In the semen from the father, there are sperms that include either X or Y chromosomes. Therefore, the sex of the baby depends on whether the sperm fertilising the egg contains an X or Y chromosome. In other words, as stated in the verse, the factor determining the sex of the baby is the semen, which comes from the father. This knowledge, which could not have been known at the time when the Qur'an was revealed, is evidence to the fact that the Qur'an is the Word of Allah.
Chromosomes are the main elements in determining sex. Two of the 46 chromosomes that determine the structure of a human being are identified as the sex chromosomes. These two chromosomes are called "XY" in males, and "XX" in females, because the shapes of the chromosomes resemble these letters. The Y chromosome carries the genes that code for masculinity, while the X chromosome carries the genes that code for femininity.
The formation of a new human being begins with the cross combination of one of these chromosomes, which exist in males and females in pairs. In females, both components of the sex cell, which divides into two during ovulation, carry X chromosomes. The sex cell of a male, on the other hand, produces two different kinds of sperm, one that contains X chromosomes and the other Y chromosomes. If an X chromosome from the female unites with a sperm that contains an X chromosome, then the baby is female. If it unites with the sperm that contains a Y chromosome, the baby is male.
In other words, a baby's sex is determined by which chromosome from the male unites with the female's ovum.
None of this was known until the discovery of genes in the 20th century. Indeed, in many cultures, it was believed that a baby's sex was determined by the female. That was why women were blamed when they gave birth to girls.
Fourteen centuries before human genes were discovered, however, the Qur'an revealed information that denies this superstition, and referred to the origin of sex lying not with women, but with the semen deriving from men.
The " Alaq" Clinging to the Uterus
In the first phase of its development, the baby in the mother's womb is in the form of a zygote, which clings to the uterus in order to take nourishment from the mother's blood. In the picture above is a zygote, which looks like a piece of flesh. This formation, which has been discovered by modern embryology, was miraculously stated in the Qur'an 14 centuries ago with the word "alaq," which means "a thing that clings to some place" and is used to describe leeches that cling to a body to suck blood.
If we continue to examine the facts announced to us in the Qur'an, about the formation of human beings, we again encounter some very important scientific truth.
When the sperm of the male unites with the ovum of the female, the essence of the baby to be born is formed. This single cell, known as a "zygote" in biology, will instantly begin reproducing by dividing, and eventually become a "piece of flesh," called an embryo. This, of course, can only be seen by human beings with the aid of a microscope.
The embryo, however, does not spend its developmental period in a void. It clings to the uterus, with something like roots that is firmly fixed to the earth by its tendrils. Through this bond, the embryo can obtain the substances essential to its development from the mother's body.85
Here, an important miracle of the Qur'an is revealed. While referring to the embryo developing in the mother's womb, Allah uses the word "alaq" in the Qur'an:
Recite: In the name of your Lord Who created man from alaq. Recite: And your Lord is the Most Generous. (Qur'an, 96:1-3)
The meaning of the word "alaq" in Arabic is "a thing that clings to some place." The word is literally used to describe leeches that cling to a body to suck blood.
Certainly, the use of such a specific word for the embryo developing in the mother's womb, proves once again that the Qur'an is the Word of Allah, the Lord of all the Worlds.
The Wrapping of Muscles over the Bones
Another important item of information provided in the verses of the Qur'an is the developmental stages of a human being in the mother's womb. It is stated in these verses that in the mother's womb, the bones develop first, and then the muscles form which wrap around them.
[We] then formed the drop into a clot and formed the clot into a lump and formed the lump into bones and clothed the bones in flesh; and then brought him into being as another creature. Blessed be Allah, the Best of Creators! (Qur'an, 23:14)
The bones of the baby completing its development in the mother's womb are clothed with flesh during one particular stage exactly as stated in the Qur’an.
Embryology is the branch of science that studies the development of the embryo in the mother's womb. Until very recently, embryologists assumed that the bones and muscles in an embryo developed at the same time. Yet, advanced microscopic research conducted by virtue of new technological developments has revealed that the revelation of the Qur'an is word for word correct.
These observations at the microscopic level showed that the development inside the mother's womb takes place in just the way it is described in these verses. First, the cartilage tissue of the embryo ossifies. Then, muscular cells that are selected from amongst the tissue around the bones come together and wrap around the bones.
This event is described in a scientific publication titled Developing Human in the following words:
… [T]he 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… The stage of clothing with muscle occurs during the 8th week…86
In short, developmental stages of man, as described in the Qur'an, are in perfect harmony with the findings of modern embryology.
Many stages of a baby's development in the mother's womb are related in the Qur'an. As described in Surat al-Muminun 14, the cartilage of the embryo in the mother's womb ossifies first. Then these bones are covered with muscle cells. Allah describes this development with the verse: "… [We then] formed the lump into bones and clothed the bones in flesh."
Three Dark Stages of the Baby in the Womb
In the Qur'an, it is related that man is created through a three-stage process in the mother's womb.
... He creates you stage by stage in your mothers' wombs in threefold darkness. That is Allah, your Lord. Sovereignty is His. There is no god but Him. So what has made you deviate? (Qur'an, 39:6)
The expression "fee thulumatin thalathin," translated into English as "a threefold darkness," indicates three dark regions involved during the development of the embryo. These are:
The darkness of the abdomen
The darkness of the womb
The darkness of the placenta
As we have seen, modern biology has revealed that the embryological development of the baby takes place in the manner revealed in the verse, in three dark regions. Moreover, advances in the science of embryology show that these regions consist of three layers each.
The lateral abdominal wall comprises three layers: the external oblique, the internal oblique, and transverses abdominis muscles.87
Similarly, the wall of the womb also consists of three layers: the epimetrium, the myometrium and the endometrium.88
Similarly again, the placenta surrounding the embryo also consists of three layers: the amnion (the internal membrane around the fetus), the chorion (the middle amnion layer) and the decidua (outer amnion layer.)89
It is also pointed out in this verse that a human being is created in the mother's womb in three distinct stages.
Indeed, modern biology has also revealed that the baby's embryological development takes place in three distinct regions in the mother's womb. Today, in all the embryology textbooks studied in departments of medicine, this subject is taken as an element of basic knowledge. For instance, in Basic Human Embryology, a fundamental reference text in the field of embryology, this fact is stated as follows:
The life in the uterus has three stages: pre-embryonic; first two and a half weeks, embryonic; until the end of the eight week, and fetal; from the eight week to labor.90
These phases refer to the different developmental stages of a baby. In brief, the main characteristics of these developmental stages are as follows:
- Pre-embryonic Stage
In this first phase, the zygote grows by division, and when it becomes a cell cluster, it buries itself in the wall of the uterus. While they continue growing, the cells organize themselves in three layers.
- Embryonic Stage
The second phase lasts for five and a half weeks, during which the baby is referred to as an "embryo." During this stage, the basic organs and systems of the body start to appear from the cell layers.
- Foetal Stage
From this stage onward, the embryo is called a "foetus." This phase begins at the eighth week of gestation, and lasts until the moment of birth. The distinctive characteristic of this stage is that the foetus looks much like a human being, with its face, hands and feet. Although it is only 3 cm long initially, all of its organs have become apparent. This phase lasts for about 30 weeks, and development continues until the week of delivery.
Information on the development in the mother's womb became available only after observations with modern devices. Yet, just like many other scientific facts, in a miraculous way, Allah draws our attention to these items of information in the verses of the Qur'an. The fact that such detailed and accurate information was given in the Qur'an at a time when people had scarce information on medical matters is clear evidence that the Qur'an is the Word of Allah.
In Surat az-Zumar 6, it is pointed out that man is created in the mother's womb in three distinct regions. Indeed, modern embryology has revealed that the baby's embryological development takes place in three distinct regions in the mother's womb.
