Mankind is a single nation. So Allah raised prophets as bearers of good news and as warners, and He revealed with them the Book with truth, that it might judge between people concerning that in which they differed. And none but the very people who were given it differed about it after clear arguments had come to them, envying one another. So Allah has guided by His will those who believe to the truth about which they differed. And Allah guides whom He pleases to the right path.
