Men were one nation once, and God sent prophets with good tidings and with warnings, and sent down with them the Book in truth, to judge between men in that wherein they disagreed; but none did disagree therein save those who had been given it after that manifest signs had come to them, through greed amongst themselves; and God guided those who did believe to that truth concerning which they disagreed by His permission, for God guides whom He will unto the right path.
