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 And of Moses' folk there is a community who lead with truth and establish justice therewith. 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 When it was said to them: 'Dwell in this village, and eat of whatever you please; and say, "Unburdening" and enter the gate prostrating, We will forgive you your sins and increase the gooddoers' 161 The wicked amongst them changed what was said for other words. Therefore We sent down upon them from heaven a punishment for their evil doing. 162
