Today we know that the cell division process, meiosis, happens in 8 phases.
The pair of chromosomes divide in eight stages, however this was portrayed in the Quran 1400 years before it was discovered.
٦ خَلَقَكُمْ مِنْ نَفْسٍ وَاحِدَةٍ ثُمَّ جَعَلَ مِنْهَا زَوْجَهَا وَأَنْزَلَ لَكُمْ مِنَ الْأَنْعَامِ ثَمَانِيَةَ أَزْوَاجٍ ۚ يَخْلُقُكُمْ فِي بُطُونِ أُمَّهَاتِكُمْ خَلْقًا مِنْ بَعْدِ خَلْقٍ فِي ظُلُمَاتٍ ثَلَاثٍ ۚ ذَٰلِكُمُ اللَّهُ رَبُّكُمْ لَهُ الْمُلْكُ ۖ لَا إِلَٰهَ إِلَّا هُوَ ۖ فَأَنَّىٰ تُصْرَفُونَ
"Eight pairs He creates you in the wombs of your mothers" today we know that in sexually reproducing organisms the pair of chromosomes divide in eight stages. Cattle and humans are sexually reproducing organisms and their cells divide by meiosis. No mistakes in the Quran.
How could an illiterate man who lived 1400 years ago have known about the 8 stages of meiosis?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
