Say thou: O mankind! verily I am the apostle of Allah unto you all - of Him whose is the dominion of the heavens and the earth. No god is there but He; He giveth life and causeth to die. Believe then in Allah and His prophet, the unlettered prophet, who believeth in Allah and His words, and follow him that haply ye may be guided. 158 And of Moses' folk there is a community who lead with truth and establish justice therewith. 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 But those of them who did wrong changed the word which had been told them for another saying, and We sent down upon them wrath from heaven for their wrongdoing. 162
