[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 (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 when it was said to them, 'Dwell in this township and eat of it wherever you will; and say, Unburdening; and enter in at the gate, prostrating; We will forgive you your transgressions, and increase the good-doers.' 161 The wicked among them changed and perverted the word We had spoken to a word unpronounced; so We sent from heaven retribution on them for all their wickedness. 162
