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 are some whose guidance and Judgment are based on the Truth. 159 And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves. 160 And recall when it was said to them: 'Dwell in this town and eat plentifully of whatever you please, and say: "Repentance", and enter the gate prostrate. We shall forgive you your sins and shall bestow further favours on those who do good.' 161 But the transgressors among them changed the word from that which had been given them so we sent on them a plague from heaven. For that they repeatedly transgressed. 162
