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 Of the people of Moses there is a section who guide and do justice in the light of truth. 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 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
