In the Qur’an, Allaah speaks about the stages of man’s embryonic development:

“ We created man from an extract of clay.Then We made him as a drop in a place of settlement, firmly fixed. Then We made the drop into an alaqah (leech, suspended thing,and blood clot), then We made the alaqah into a mudghah (chewed substance)... .”[Qur’an : 23 : 12-14]

Literally, the Arabic word alaqah has three meanings: (1) leech, (2) suspended thing, and (3) blood clot. In comparing a leech to an embryo in the alaqah stage, we find similarity between the two, as we can see in figure 1. Also, the embryo at this stage obtains nourishment from the blood of the mother, similar to the leech, which feeds on the blood of others.

The second meaning of the word alaqah is “suspended thing.” This is what we can see in figures 2 and 3, the suspension of the embryo, during the alaqah stage, in the womb of the mother.

The third meaning of the word alaqah is “blood clot.” We find that the external appearance of the embryo and its sacs during the alaqah stage is similar to that of a blood clot. This is due to the presence of relatively large amounts of blood present in the embryo during this stage. Also during this stage,the blood in the embryo does not circulate until the end of the third week. Thus, the embryo at this stage is like a clot of blood. So the three meanings of the word alaqah correspond accurately to the descriptions of the embryo at the alaqah stage.

The next stage mentioned in the verse is the mudghah stage.The Arabic word mudghah means “chewed substance.” If one were to take a piece of gum and chew it in his or her mouth and then compare it with an embryo at the mudghah stage, we would conclude that the embryo at the mudghah stage is similar in appearance to a chewed substance. This is because of the somites at the back of the embryo that “somewhat resemble teethmarks in a chewed substance.”3 (see figures 5 and 6).


"Then We developed out of it another creature."

This next part of Surah 23:14 implies that the bones and muscles result in the formation of another creature. This may refer to the human-like embryo that forms by the end of the eighth week. At this stage it has distinctive human characteristics and possesses the primordia of all the internal and external organs and parts. After the eighth week, the human embryo is called a fetus. This may be the new creature to which the verse refers.

"And He gave you hearing and sight and feeling and understanding."

This part of Surah 32:9 indicates that the special senses of hearing, seeing, and feeling develop in this order, which is true. The primordia of the internal ears appear before the beginning of the eyes, and the brain (the site of understanding) differentiates last.

"Then out of a piece of chewed flesh, partly formed and partly unformed."

This part of Surah 22:5 seems to indicate that the embryo is composed of both differentiated and undifferentiated tissues. For example, when the cartilage bones are differentiated, the embryonic connective tissue or mesenchyme around them is undifferentiated. It later differentiates into the muscles and ligaments attached to the bones.

"And We cause whom We will to rest in the wombs for an appointed term."

This next part of Surah 22:5 seems to imply that God determines which embryos will remain in the uterus until full term. It is well known that many embryos abort during the first month of development, and that only about 30% of zygotes that form, develop into fetuses that survive until birth. This verse has also been interpreted to mean that God determines whether the embryo will develop into a boy or girl.

The interpretation of the verses in the Qur'an referring to human development would not have been possible in the 7th century A.D., or even a hundred years ago. We can interpret them now because the science of modern Embryology affords us new understanding. Undoubtedly there are other verses in the Qur'an related to human development that will be understood in the future as our knowledge increases.


"He makes you in the wombs of your mothers in stages, one after another, in three veils of darkness."
This statement is from Surah 39:6. We do not know when it was realized that human beings underwent development in the uterus (womb), but the first known illustration of a fetus in the uterus was drawn by Leonardo da Vinci in the 15th century. In the 2nd century A.D., Galen described the placenta and fetal membranes in his book "On The Formation of the Foetus." Consequently, doctors in the 7th century A.D. likely knew that the human embryo developed in the uterus. It is unlikely that they knew that it developed in stages, even though Aristotle had described the stages of development of the chick embryo in the 4th century B.C. The realization that the human embryo develops in stages was not discussed and illustrated until the 15th century.
After the microscope was discovered in the 17th century by Leeuwenhoek descriptions were made of the early stages of the chick embryo. The staging of human embryos was not described until the 20th century. Streeter (1941) developed the first system of staging which has now been replaced by a more accurate system proposed by O'Rahilly (1972).
"The three veils of darkness" may refer to: (l) the anterior abdominal wall; (2) the uterine wall; and (3) the amniochorionic membrane (Fig. 1). Although there are other interpretations of this statement, the one presented here seems the most logical from an embryological point of view.


How could Muhammad(SAWS) have possibly known all this about fourteen hundred years ago, when scientists have only recently discovered this using advanced equipment and powerful microscopes which did not exist at that time?

Hamm and Leeuwenhoek were the first scientists to observe human sperm cells (spermatozoa) using an improved microscope in 1677 (more than 1000 years after Muhammad(SAWS)). They mistakenly thought that the sperm cell contained a miniature preformed human being that grew when it was deposited in the female genital tract. Professor Emeritus Keith L. Moore is one of the world’s most prominent scientists in the fields of anatomy and embryology and is the author of the book entitled The Developing Human, which has been translated into eight languages. This book is a scientific reference work and was chosen by a special committee in the United States as the best book authored by one person. Dr. Keith Moore is Professor Emeritus of Anatomy and Cell Biology at the University of Toronto, Toronto, Canada. There, he was Associate Dean of Basic Sciences at the Faculty of Medicine and for 8 years was the Chairman of the Department of Anatomy. In 1984, he received the most distinguished award presented in the field of anatomy in Canada, the J.C.B. Grant Award from the Canadian Association of Anatomists. He has directed many international associations, such as the Canadian and American Association of Anatomists and the Council of the Union of Biological Sciences. In 1981, during the Seventh Medical Conference in Dammam, Saudi Arabia, Professor Moore said: “It has been a great pleasure for me to help clarify statements in the Qur’an about human development. It is clear to me that these statements must have come to Muhammad(SAWS) from ALLAAH, because almost all of this knowledge was not discovered until many centuries later. This proves to me that Muhammad(SAWS) must have been a messenger of Allaah.” Consequently, Professor Moore was asked the following question:

“Does this mean that you believe that the Qur’an is the word of God (Allaah)?” He replied: “I find no difficulty in accepting this.” During one conference, Professor Moore stated: “....Because
the staging of human embryos is complex, owing to the continuous process of change during development, it is proposed that a new system of classification could be developed using the terms mentioned in the Qur’an and Sunnah (what Muhammad (SAWS) said, did, or approved of). The proposed system is simple, comprehensive, and conforms with present embryological knowledge. The intensive studies of the Qur’an and Hadith (reliably transmitted reports by the Prophet Muhammad’s (SAWS) companions of what he said, did, or approved of) in the last four years have revealed a system for classifying human embryos that is amazing since it was recorded in the seventh century A.D. Although Aristotle, the founder of the science of embryology, realized that chick embryos developed in stages from his studies of hen’s eggs in the fourth century B.C., he did not give any details about these stages. As far as it is known from the history of embryology, little was known about the staging and classification of human embryos until the twentieth century. For this reason, the descriptions of the human embryo in the Qur’an cannot be based on scientific knowledge in the seventh century. The only reasonable conclusion is: these descriptions were revealed to Muhammad(SAWS) from God(ALLAAH). He could not have known such details because he was an illiterate man with absolutely no scientific training.”
