In the Holy Quran, God 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)... " (Quran,
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.
Figure 1: Drawings illustrating the
similarities in appearance between a leech and a human embryo at the
alaqah stage. (Leech drawing from Human Development as Described in
the Quran and Sunnah, Moore and others, p. 37, modified from
Integrated Principles of Zoology, Hickman and others. Embryo drawing
from The Developing Human, Moore and Persaud, 5th ed., p. 73.)
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.
Figure 2: We can see in this diagram
the suspension of an embryo during the alaqah stage in the womb
(uterus) of the mother. (The Developing Human, Moore and Persaud,
5th ed., p. 66.) (Click on the image to enlarge it.)
Figure 3: In this photomicrograph, we
can see the suspension of an embryo (marked B) during the alaqah
stage (about 15 days old) in the womb of the mother. The actual size of
the embryo is about 0.6 mm. (The Developing Human, Moore, 3rd ed.,
p. 66, from Histology, Leeson and Leeson.)
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 (see figure 4). 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.
Figure 4: Diagram of the primitive
cardiovascular system in an embryo during the alaqah stage. The
external appearance of the embryo and its sacs is similar to that of a
blood clot, due to the presence of relatively large amounts of blood
present in the embryo. (The Developing Human, Moore, 5th ed., p.
65.) (Click on the image to enlarge it.)
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 acquires the appearance of a chewed substance. This
is because of the somites at the back of the embryo that “somewhat resemble
teethmarks in a chewed substance.” (see figures 5 and 6).
Figure 5: Photograph of an embryo at
the mudghah stage (28 days old). The embryo at this stage acquires
the appearance of a chewed substance, because the somites at the back of
the embryo somewhat resemble teeth marks in a chewed substance. The
actual size of the embryo is 4 mm. (The Developing Human, Moore and
Persaud, 5th ed., p. 82, from Professor Hideo Nishimura, Kyoto University,
Kyoto, Japan.)
Figure 6: When comparing the
appearance of an embryo at the mudghah stage with a piece of gum
that has been chewed, we find similarity between the two. A) Drawing of an embryo at the mudghah stage. We can see
here the somites at the back of the embryo that look like teeth marks. (The

How could Muhammad (MPBUH)
have possibly known all this 1400 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 (MPBUH)). 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 Quran about human development. It is clear to
me that these statements must have come to Muhammad from God, because almost all
of this knowledge was not discovered until many centuries later. This proves to
me that Muhammad must have been a messenger of God.”
Consequently, Professor Moore was asked the
following question: “Does this mean that you believe that the Quran is the word
of God?” 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 Quran and Sunnah (what Muhammad (MPBUH)
said, did, or approved of). The proposed system is simple, comprehensive, and
conforms with present embryological knowledge. The intensive studies of the
Quran and hadeeth (reliably transmitted reports by the Prophet
Muhammad’s (MPBUH) 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 Quran cannot be based on scientific
knowledge in the seventh century. The only reasonable conclusion is: these
descriptions were revealed to Muhammad from God. He could not have known such
details because he was an illiterate man with absolutely no scientific
training.”
