Say, [O Muhammad], "O mankind, indeed I am the Messenger of Allah to you all, [from Him] to whom belongs the dominion of the heavens and the earth. There is no deity except Him; He gives life and causes death." So believe in Allah and His Messenger, the unlettered prophet, who believes in Allah and His words, and follow him that you may be guided. 158 Among the people of Moses is a section that shows the way to the truth, and deals justly in accordance with it. 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 what time it was said unto them: dwell in yonder town and eat plentifully therefrom anything ye list, and say: fergiveness, and enter the gate bowing; and We will forgive you your trespasses: anon We will increase unto the well-doers. 161 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
