Was Quran revealed in English?<quoted text>
Are you saying the koran does not say human conception starts with a clot of blood? So what does the koran say?
Quran uses the Arabic term "ALAQ" and not English "Clot of Blood".
ALAQ has many sense of meanings. In reality one of the meaning is "some thing which clings" (Like the insects which suck blood), so in the initial stages of pregnancy, the "mingled sperm" is like some thing which clings to the womb.... and this is exactly as we discovered "only recently".
So those who translated ALAQ as "Clot of Blood" made a mistake, it was not the mistake of Arabic Quran. It was not prophet who said "Alaq" means Clot of Blood. Some one translated it, based on the look of fetus in the early stage of pregnancy.
So there is and there was nothing wrong in Quran, when it was revealed 1400 years ago.
If we did not had the original manuscript of Quran or someone had "inserted" his own interpretation of ALAQ, we could have problems as we have in Bible.
Allah Knows Best
