“Verily, We fashioned man from a small quantity of mingled (amchaj) liquids . . .”
Qur’an - Surah al-Insaan (Man) 76:2
“As we know, this liquid is composed of secretions from the following glands: the testicles, the seminal vesicles, the prostate and the glands annexed to the urinary tract.” (What is the Origin of Man by Dr. Maurice Bucaille)
12. We fashioned man from the quintessence (sulatat) of a clay (tiyn - water and earth).
13. Then placed him as a drop (nutfah - of seed) in a place of rest, firmly fixed (qararin makin);
14. We fashioned the thing which clings (alaq) into a lump of chewed flesh (mudrat) and We fashioned the chewed flesh (mudrat) into bones and We clothed the bones with intact flesh (lahm), and then produced it as another creation. So blessed be Allaah, the Best of creators!
Qur’an - Surah al-Mu`minoon (The Cleaving) 23:12-14 See also 39:6 and 77:20-22.
When the first spermatozoon penetrates the human egg, the egg envelopes play a crucial role in fertilization. The egg envelopes are the outermost layers of the egg cell that surround the plasma membrane. They are made up of two layers: the zona pellucida and the corona radiata. The zona pellucida is a glycoprotein layer that surrounds the oocyte and is essential for sperm binding and penetration. The corona radiata is a layer of follicle cells that surrounds the zona pellucida and helps to protect the oocyte from damage. After the spermatozoon penetrates the zona pellucida, the cortical granules in the egg release their contents, which cause the zona pellucida to harden and become impenetrable to other sperm. This process is called the fertilization envelope and is the slow block to polyspermy (if more than one spermatozoon should penetrate the egg, the fertilised egg goes to waste). Refer to Qur’an 23:13.
The human fertilised egg, eventually implants itself to the lining of the uterus. Only when this attachment occurs does the pregnancy begins. Without the implantation, the fertilised egg goes to waste. Refer to Qur’an 23:14.
45. “[God] fashioned the two of a pair, the male and the female,
46. from a small quantity of sperm (nutfah) when it is poured out.”
Qur’an – Surah an-Najm (The Star) 53:45-6
“The male fertilizing agent, the spermatozoon, contains the hemichromosome that is to determine the sex of the future individual.” (What is the Origin of Man by Dr. Maurice Bucaille)
