Say [O Muhammad]: "O mankind! Verily, I am an apostle of God to all of you, [sent by Him] unto whom the dominion over the heavens and the earth belongs! There is no deity save Him; He [alone] grants life and deals death!" Believe, then, in God and His Apostle - the unlettered Prophet who believes in God and His words - and follow him, so that you might find guidance! 158 Of the people of Moses there is a section who guide and do justice in the light of truth. 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 they were told, "Settle down in this town, eat as you wish, seek forgiveness and enter the gate prostrating yourselves (in obedience to the Lord) and We will forgive you your sins and increase the reward of the righteous people, 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
