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, nations. And We revealed to Moses, when his people asked him for water: 'Strike with thy staff the rock'; and there gushed forth from it twelve fountains all the people knew now their drinking-place. And We outspread the cloud to overshadow them, and We sent down manna and quails upon them: 'Eat of the good things wherewith We have supplied you.' And they worked no wrong upon Us, but themselves they wronged. 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
