(Muhammad), tell them, "People, I have come to you all as the Messengers of God, to whom the Kingdom of the heavens and the earth belongs. There is no God but He. In His hands are life and death. Have faith in God and His Messengers, the unlettered Prophet who believes in God and His words. Follow him so that you will perhaps have guidance." 158 Among the people of Moses are some whose guidance and Judgment are based on the Truth. 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 to them, 'Dwell in this township and eat of it wherever you will; and say, Unburdening; and enter in at the gate, prostrating; We will forgive you your transgressions, and increase the good-doers.' 161 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
