[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 And among the people of Moses is a community which guides by truth and by it establishes justice. 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 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 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
