Say: O people! surely I am the Apostle of Allah to you all, of Him Whose is the kingdom of the heavens and the earth there is no god but He; He brings to life and causes to die therefore believe in Allah and His apostle, the Ummi Prophet who believes in Allah and His words, and follow him so that you may walk in the right way. 158 And of Musa's people was a party who guided (people) with the truth, and thereby did they do justice. 159 And We cut them up into twelve tribes as communities. And We revealed unto Musa, when his people asked him for drink: Smite the rock with thy rod. Then gushed forth therefrom twelve springs: every people already knew their drinking-places. And We shaded them with thick clouds, and We sent down upon them the manna and the quails, saying: eat of the clean things wherewith We have provided you. And they wronged not Us, but themselves they were wont to wrong. 160 And when it was said to them: "Live in this land and eat of its produce wheresoever you like, and ask for remission of your sins, but pass through the gates with submission (and not pride), We shall forgive your trespasses, and give to those who are righteous abundance," 161 the transgressors among them substituted something else for the word they had been given. So We sent them a punishment from heaven for their wrongdoing. 162
