(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 And among the people of Moses is a community which guides by truth and by it establishes justice. 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 When they were told, "Settle down in the town and eat wherever you wish in it, and pray for forgiveness and enter the gate in humility: We shall forgive you your sins and shall bestow further favours upon those who do good," 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
