(In the beginning) all the people agreed upon the same Din (Religion. Later, when differences emerged among them,) Allah sent His Messengers as Bearers of good news and Warners and sent down with them the Book based on Truth, so that it might judge those matters among the people in which they had developed differences. Then only those very people whom the Book was given differed about it, despite the fact that the clear Signs had come to them. (And they differed also) because of mere jealousy and malice among themselves. Then Allah, by His Command, made the believers understand that matter of Truth about which they had differed. And Allah guides whom He pleases to the straight road.
