Say: 'O mankind, I am the Messenger of Allah to you all. His is the kingdom in the heavens and the earth. There is no god except He. He revives and causes to die. Therefore, believe in Allah and His Messenger, the Unlettered Prophet, who believes in Allah and His Words. Follow him in order that you are guided.' 158 Among the people of Moses is a section that shows the way to the truth, and deals justly in accordance with it. 159 We divided them into twelve tribes, nations; and We inspired Moses, when his people asked him for water, saying: Smite with thy staff the rock! And there gushed forth therefrom twelve springs, so that each tribe knew their drinking-place. And we caused the white cloud to overshadow them and sent down for them the manna and the quails (saying): Eat of the good things wherewith we have provided you. They wronged Us not, but they were wont to wrong 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 Then the wrong-doers among them substituted another word in place of the one told them. So We sent upon them a scourge from the heaven as a punishment for their Wrong-doing. 162
