The people were one nation. Then Allah sent forth Prophets to give them glad tidings and to warn them; and with them He sent down the Book with the truth, that He might rule between the people in that which they differ. Only those to whom it had been given differed about it after the clear verses had come to them, transgressing between themselves. Then Allah guided those who believed concerning that which they were at variance in the truth, by His permission. Allah guides whom He will to the Straight Path.
