Assalamualykum.
Some unbelievers claim that the Muslims at the time of Muhammad (S.A.W) knew about Human Embryology. They claim they used to cut Human bodies and study these things and that's why when verses related to Human embryology were revealed those verses didn't confuse them.
My question is, as most of the scientific miracles of the Quran were unknown at that time, so what attracted the people towards Islam at that time? And , what assured them that Islam is the true religion?
Please Help.
Brother, stop asking too many questions, it's not good.
Firstly, people in Arabia, for example, Jews in Medina would regularly tell their people that a man will come, so the arabs, when the prophet came accepted him straight away, in fact the jews would say to the pagans, a prophet will arise here, and we will fight with him against you to establish the religion of Ibraheem (May Allah send peace upon him).
Also, the prophet performed many miracles with the help of Allah, he split the moon etc.
PLEASE, if you want to know how people accepted him etc, go and listen to his biography (May Allah send peace and blessings upon him).
Listen to the one by Mufti menk, my faith increased so much.
But yeah, most people accepted him, when he entered Medina because they were awaiting for a prophet to come who would re-establish the religion of Ibraheem (May Allah send peace and blessings upon him).
