Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright. 158 Among the people of Moses is a section that shows the way to the truth, and deals justly in accordance with it. 159 And We cut them up into twelve tribes as communities. And We revealed unto Musa, when his people asked him for drink: Smite the rock with thy rod. Then gushed forth therefrom twelve springs: every people already knew their drinking-places. And We shaded them with thick clouds, and We sent down upon them the manna and the quails, saying: eat of the clean things wherewith We have provided you. And they wronged not Us, but themselves they were wont to wrong. 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 So the unjust among them changed the words, contrary to what they had been commanded – consequently We sent down upon them a punishment from the sky – the recompense of their injustice. 162
