Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided." 158 Among the people of Moses' there was a party who guided others in the way of the truth and established justice in its light. 159 We divided them into twelve tribes, each a nation. And when his people demanded drink, We revealed to Moses: 'Strike the rock with your staff' Thereupon twelve springs gushed from the rock and each tribe knew its drinking place. We caused the clouds to cast their shadow over them, and sent down for them manna and quails, saying: 'Eat of the good things We have provided for you' Indeed, they did Us no wrong, but they wronged 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 Then the wrong-doers among them substituted another word in place of the one told them. So We sent upon them a scourge from the heaven as a punishment for their Wrong-doing. 162
