Say, "People, I am God's Messenger to you all, He has sovereignty over the heavens and the earth. There is no god but Him. He ordains life and death, so believe in God and His Messenger, the unlettered prophet who believes in God and His words. Follow him so that you may be rightly guided." 158 And among the people of Moses is a community which guides by truth and by it establishes 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) when it was said to them: "Dwell in this town (Jerusalem) and eat therefrom wherever you wish, and say, '(O Allah) forgive our sins'; and enter the gate prostrate (bowing with humility). We shall forgive you your wrong-doings. We shall increase (the reward) for the good-doers." 161 Then those of them who did wrong changed the word that had been told them for another, whereupon We sent upon them a scourge from the heaven for they were wont to transgress. 162
