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 them into twelve tribes or nations. We directed Moses by inspiration, when his (thirsty) people asked him for water: "Strike the rock with thy staff": out of it there gushed forth twelve springs: Each group knew its own place for water. We gave them the shade of clouds, and sent down to them manna and quails, (saying): "Eat of the good things We have provided for you": (but they rebelled); to Us they did no harm, but they harmed their own souls. 160 And [mention, O Muhammad], when it was said to them, "Dwell in this city and eat from it wherever you will and say, 'Relieve us of our burdens,' and enter the gate bowing humbly; We will [then] forgive you your sins. We will increase the doers of good [in goodness and reward]." 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
