Say: 'O mankind, I am the Messenger of Allah to you all. His is the kingdom in the heavens and the earth. There is no god except He. He revives and causes to die. Therefore, believe in Allah and His Messenger, the Unlettered Prophet, who believes in Allah and His Words. Follow him in order that you are guided.' 158 AND AMONG the folk of Moses there have been people who would guide [others] in the way of the truth and act justly in its light. 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 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 But those among them who did wrong changed the word that had been told to them. So We sent on them a torment from heaven in return for their wrong-doings. 162
