Say thou: O mankind! verily I am the apostle of Allah unto you all - of Him whose is the dominion of the heavens and the earth. No god is there but He; He giveth life and causeth to die. Believe then in Allah and His prophet, the unlettered prophet, who believeth in Allah and His words, and follow him that haply ye may be guided. 158 And of Moses' folk there is a community who lead with truth and establish justice therewith. 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 But those among them who were bent on wrongdoing substituted another saying for that which they had been given: and so We let loose against them a plague from heaven in requital of all their evil doings. 162
