Say, "People, I am God's Messenger to you all, He has sovereignty over the heavens and the earth. There is no god but Him. He ordains life and death, so believe in God and His Messenger, the unlettered prophet who believes in God and His words. Follow him so that you may be rightly guided." 158 And of the people of Musa there is a community guiding others by the truth and judging thereby. 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 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
