Mankind was a single community. Then Allah sent out Prophets bringing good news and giving warning, and with them He sent down the Book with truth to decide between people regarding their differences. Only those who were given it differed about it, after the Clear Signs had come to them, envying one another. Then, by His permission, Allah guided those who had iman to the truth of that about which they had differed. Allah guides whomever He wills to a straight path.
