In the beginning all the people followed the same way. (Afterwards there came a change and differences arose). Then Allah sent Prophets to give good tidings to those who followed the Right Way and warnings to those who swerved from it. And He sent down with them the Book based on the Truth so that it should judge between the people concerning their differences. (Differences arose not because people were not given the knowledge of the Truth in the beginning, nay), differences arose between those very people who had been given clear teachings, and (for no other reasons than that) they wanted to tyrannize over one another. So Allah, by His leave, guided those who believed in the Prophets to the Truth about which they had differed; AIIah guides whomever He pleases to the Right Way.
