Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright. 158 Among the people of Moses is a section that shows the way to the truth, and deals justly in accordance with it. 159 We divided them up into twelve tribes, each a whole community, and We revealed Our will to Moses, when his people asked for water, saying, "Strike the rock with your staff." Twelve springs gushed from it and each tribe knew its drinking place. We caused the clouds to draw their shadow over them and sent down for them manna and quails, saying, "Eat the good things We have given you." They did not wrong Us; rather it was themselves they wronged. 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 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
