Say, [O Muhammad], "O mankind, indeed I am the Messenger of Allah to you all, [from Him] to whom belongs the dominion of the heavens and the earth. There is no deity except Him; He gives life and causes death." So believe in Allah and His Messenger, the unlettered prophet, who believes in Allah and His words, and follow him that you may be guided. 158 AND AMONG the folk of Moses there have been people who would guide [others] in the way of the truth and act justly in its light. 159 We divided them into twelve (different) tribes. When his people asked for water, We said to Moses: "Strike the rock with your staff;" and behold, twelve springs of water gushed forth, so that each of the tribes had a place of its own to drink; and We made the clouds spread shade over them and sent for them manna and quails (and said): "Eat of the good things We have provided for you." But (by disobeying) they did not harm Us, they harmed themselves. 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 Then the evildoers of them substituted a saying other than that which had been said to them; so We sent down upon them wrath out of heaven for their evildoing. 162
