Say, "People, I am God's Messenger to you all, He has sovereignty over the heavens and the earth. There is no god but Him. He ordains life and death, so believe in God and His Messenger, the unlettered prophet who believes in God and His words. Follow him so that you may be rightly 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 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
