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 among the people of Moses is a community which guides by truth and by it establishes justice. 159 And We divided them into twelve tribes, forming them into communities. When his people asked Moses for water We directed him: 'Smite the rock with your rod.' Then twelve springs gushed forth from the rock and every people knew their drinking-places. And We caused thick clouds to provide them shade, and We sent down upon them manna and quails, saying: 'Eat of the clean things that We have provided you.' They wronged not Us, but it was themselves that they wronged. 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 the transgressors among them substituted something else for the word they had been given. So We sent them a punishment from heaven for their wrongdoing. 162
