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 Among the people of Moses are some whose guidance and Judgment are based on the Truth. 159 And We divided them into twelve tribes (as distinct) nations. We directed Musa (Moses) by inspiration, when his people asked him for water, (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs: each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm 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 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
