Some Scientific marvels of the Qur'an (OCEAN)

Allah likens the state of an unbeliever to that of a person in the dark depths of the ocean. He cannot see his hand in front of his face and his under layers of darkness. Remember that the Prophet (p) had never ever seen the ocean before nor did anyone ever dive to the deep recesses of the ocean at that time. People didn't know, at that time, that the bottom of the ocean is dark. (24:40)
