[Say, O Muhammad]: 'O men! I am Allah's Messenger to you all - of Him to Whom belongs the dominion of the heavens and the earth. There is no god but He. He grants life and deals death. Have faith then, in Allah and in His Messenger, the ummi Prophet who believes in Allah and His words; and follow him so that you may be guided aright.' 158 Yet among the people of Moses there was a nation who preached the truth and acted justly. 159 We divided them into twelve (different) tribes. When his people asked for water, We said to Moses: "Strike the rock with your staff;" and behold, twelve springs of water gushed forth, so that each of the tribes had a place of its own to drink; and We made the clouds spread shade over them and sent for them manna and quails (and said): "Eat of the good things We have provided for you." But (by disobeying) they did not harm Us, they harmed themselves. 160 And when it was said unto them: Dwell in this township and eat therefrom whence ye will, and say "Repentance," and enter the gate prostrate; We shall forgive you your sins; We shall increase (reward) for the right-doers. 161 But those who wronged among them changed [the words] to a statement other than that which had been said to them. So We sent upon them a punishment from the sky for the wrong that they were doing. 162
