One Religion

Humanity was once a single community, but then they differed. So, Allah sent prophets as bearers of good news and warners, and revealed to them the Scripture in truth to judge between people in their disputes. Yet none disputed it except those who had received it, after clear proofs had come to them, out of jealousy. Then Allah, by His grace, guided the believers to the truth regarding those disputes.

2:213Mankind were one community, and Allah sent (unto them) prophets as bearers of good tidings and as warners, and revealed therewith the Scripture with the truth that it might judge between mankind concerning that wherein they differed. And only those unto whom (the Scripture) was given differed concerning it, after clear proofs had come unto them, through hatred one of another. And Allah by His Will guided those who believe unto the truth of that concerning which they differed. Allah guideth whom He will unto a straight path.
