Say: "O men, I am verily the apostle of God to you all. His whose kingdom extends over the heavens and the earth. There is no god but He, the giver of life and death. So believe in God and the messenger, the gentile Prophet, sent by Him, who believes in God and His messages. Obey him; you may haply be guided aright." 158 Of the people of Moses there is a nation who guide by the truth, and by it act with justice. 159 We divided the descendants of Israel into twelve tribes and told Moses to strike the rock with his staff to let twelve fountains gush out therefrom; his people had asked him to supply them with water. The twelve flowing springs were divided among them (a spring for each tribe) and each tribe knew its drinking place well. We provided them with shade from the clouds, sent down manna and quails to them for food, and told them to eat the pure things which We had given them. They did not do injustice to Us but they wronged themselves. 160 And recall when it was said to them: 'Dwell in this town and eat plentifully of whatever you please, and say: "Repentance", and enter the gate prostrate. We shall forgive you your sins and shall bestow further favours on those who do good.' 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
