The Koran is known to be the first book to give microscopic details of human embryology, hundreds of years before the discovery of the microscope! The Koran contains information on embryology, which was not discovered till about 30 years back, and certain details were new even to modern scientists but were immediately confirmed as being accurate:
Then We placed him as a drop (of seed) in a safe lodging. Then fashioned the seed into a leech (23:13-14)
If a microscopic picture of a human embryo of days 7-24 is taken and placed next to a picture of a leech, they both look identical. Not only do they look the same but they function in the same way too. Just like a leech derives nourishment from its host's blood, the embryo derives nourishment from the decidua or the pregnant endometrium. Keith L. Moore, a world authority on embryology, states in his book, The Developing Human (1998): "Reference (in the Koran) is also made to the leech-like appearance of the early embryo. The four week embryo shown looks like a leech or blood sucker."
As in the verses quoted above (23:13-14), it can be noted that the varying evolutionary states from sperm to embryo are described with a faith-promoting clarity. When Keith Moore, Head of the department of anatomy, at the University of Toronto, was shown verses of the Quran dealing with the microscopic stages of the human embryo, he was astonished and stated, after being unable to explain as how microscopic details of the embryo could be so accurately described in a book written before the discovery of the microscope:
"It is clear to me that these statements (in the Quran on embryology) must have come to Muhammad from God. This proves to me that Muhammad must have been the messenger of God or Allah."
Gerald C. Goeringer who is Professor and Coordinator of Medical Embryology in the Department of Cell Biology, School of Medicine, Georgetown University, Washington DC, USA. remarks:
"...In a relatively few ayahs (Qur'anic verses) is contained a rather comprehensive description of human development. No such distinct and complete record of human development such as classification, terminology, and description existed previously. In most, if not all instances, this description antedates by many centuries the recording of the various stages of human embryonic and fetal development recorded in the traditional scientific literature."
THE INVISIBLE BARRIER
He has made the two seas to flow freely (so that) they meet together:
Between them is a barrier, which they cannot encroach.
Which then of the bounties of your Lord will you deny? (55:19-21)
What the scientists discovered only recently was stated by the Koran fourteen centuries ago. It is a very unusual phenomenon that the Mediterranean and Atlantic ocean differ in their chemical and biological constitution. The French scientist Jacques Yves Cousteau conducted various undersea investigations at the Strait of Gibraltar and explaining these phenomena concluded:
“Unexpected fresh water springs issue from the southern and northern coasts of Gibraltar. These mammoth springs gush towards each other at angles of 45 degrees forming a reciprocal dam. Due to this fact the Mediterranean and the Atlantic Ocean cannot intermingle.”
The same fact has been elucidated in the following verse:
It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed.
One may aptly inquire: “Did Muhammad (S.A.W.) do research on the chemical and biological components of seawater to discover this unusual phenomena?”
OCEANS AND DEPTHS OF DARKNESS
Or (the Unbelievers' state) is like the depths of darkness in a vast deep ocean, overwhelmed with billow topped by billow, topped by (dark) clouds: depths of darkness, one above another: if a man stretches out his hands, he can hardly see it! f or any to whom God giveth not light, there is no light! (24:40)
Not a better and lovelier picture can be drawn as this one pertaining to the oceans containing incredible layers of darkness one above the other and topped by clouds. The average depth of the oceans is 3795 meters (12450 feet). Without protective equipment humans cannot go down below 40 meters. At 200 meters light is successively absorbed, layer by layer and prevails the darkness that goes on increasing so much so that a man cannot see his own hands.
Internal waves in the "deep ocean" have been recognized only in the past four decades ago with the help of remote sensing from space platforms
CREATION OF PAIRS
(He is) the Creator of the heavens and the earth: He has made for you pairs from among yourselves, and pairs among cattle: by this means does He multiply you: there is nothing whatever like unto Him, and He is the One that hears and sees (all things) (42:11)
