The Quran on Human Embryonic Development

The sperm does not turn into congealed (see http://www.m-w.com/dictionary/congeal ) blood.

I thank you very much for your post and appreciate your precise remark.

In this verse (14 of Chapter Al-Muminun), Abdullah Yusuf Ali translated the Arabic word alaqah as "congealed blood".
alaqah has basically three meanings:
1) Something which clings.
2) A leech-like substance.
Both descriptions are scientifically acceptable as in the very early stages the foetus clings to the wall and also appears to resemble the leech in shape. It also behaves like a leech (blood sucker) and acquires its blood supply from the mother through the placenta.
3) A blood clot. During this alaqah stage, which spans the third and fourth week of pregnancy, the blood clots within closed vessels. Hence the embryo acquires the appearance of a blood clot in addition to acquiring the appearance of a leech.

real life, you can re-visit the link I provided (in page 1 of the thread) to find out that renowned, eminent and distinguish scientists acknowledge the accuracy of the Quranic verses dealing with Embryology.


And Allah knows best.

By the end of the fourth week the infant's own heart is beating and circulating the infant's blood thru it's vessels. It is not clotted.
