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 Among the people of Moses are some whose guidance and Judgment are based on the Truth. 159 We divided them into twelve tribes, each a nation. And when his people demanded drink, We revealed to Moses: 'Strike the rock with your staff' Thereupon twelve springs gushed from the rock and each tribe knew its drinking place. We caused the clouds to cast their shadow over them, and sent down for them manna and quails, saying: 'Eat of the good things We have provided for you' Indeed, they did Us no wrong, but they wronged themselves. 160 When they were told, "Settle down in the town and eat wherever you wish in it, and pray for forgiveness and enter the gate in humility: We shall forgive you your sins and shall bestow further favours upon those who do good," 161 But those who wronged among them changed [the words] to a statement other than that which had been said to them. So We sent upon them a punishment from the sky for the wrong that they were doing. 162
