Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided." 158 And of Musa's people was a party who guided (people) with the truth, and thereby did they do justice. 159 We divided them into twelve tribes or nations. We directed Moses by inspiration, when his (thirsty) people asked him for water: "Strike the rock with thy staff": out of it there gushed forth twelve springs: Each group knew its own place for water. We gave them the shade of clouds, and sent down to them manna and quails, (saying): "Eat of the good things We have provided for you": (but they rebelled); to Us they did no harm, but they harmed their own souls. 160 And remember it was said to them: "Dwell in this town and eat therein as ye wish, but say the word of humility and enter the gate in a posture of humility: We shall forgive you your faults; We shall increase (the portion of) those who do good." 161 But those among them who did wrong changed the word that had been told to them. So We sent on them a torment from heaven in return for their wrong-doings. 162
