[Say, O Muhammad]: 'O men! I am Allah's Messenger to you all - of Him to Whom belongs the dominion of the heavens and the earth. There is no god but He. He grants life and deals death. Have faith then, in Allah and in His Messenger, the ummi Prophet who believes in Allah and His words; and follow him so that you may be guided aright.' 158 Among the people of Moses' there was a party who guided others in the way of the truth and established justice in its light. 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 And [remember] when you were told: "Dwell in this land and eat of its food as you may desire; but say, 'Remove Thou from us the burden of our sins,' and enter the gate humbly - [whereupon] We shall forgive you your sins [and] shall amply reward the doers of good." 161 But those who were unjust among them changed it for a saying other than that which had been spoken to them; so We sent upon them a pestilence from heaven because they were unjust. 162
