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 Among the people of Moses' there was a party who guided others in the way of the truth and established justice in its light. 159 And We cut them up into twelve tribes, nations. And We revealed to Moses, when his people asked him for water: 'Strike with thy staff the rock'; and there gushed forth from it twelve fountains all the people knew now their drinking-place. And We outspread the cloud to overshadow them, and We sent down manna and quails upon them: 'Eat of the good things wherewith We have supplied you.' And they worked no wrong upon Us, but themselves they wronged. 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 But those among them who were bent on wrongdoing substituted another saying for that which they had been given: and so We let loose against them a plague from heaven in requital of all their evil doings. 162
