Say thou: O mankind! verily I am the apostle of Allah unto you all - of Him whose is the dominion of the heavens and the earth. No god is there but He; He giveth life and causeth to die. Believe then in Allah and His prophet, the unlettered prophet, who believeth in Allah and His words, and follow him that haply ye may be guided. 158 Yet among the people of Moses there was a nation who preached the truth and acted justly. 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 When it was said to them: 'Dwell in this village, and eat of whatever you please; and say, "Unburdening" and enter the gate prostrating, We will forgive you your sins and increase the gooddoers' 161 But those who wronged among them changed [the words] to a statement other than that which had been said to them. So We sent upon them a punishment from the sky for the wrong that they were doing. 162
