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 are some whose guidance and Judgment are based on the Truth. 159 We divided them into twelve tribes, nations; and We inspired Moses, when his people asked him for water, saying: Smite with thy staff the rock! And there gushed forth therefrom twelve springs, so that each tribe knew their drinking-place. And we caused the white cloud to overshadow them and sent down for them the manna and the quails (saying): Eat of the good things wherewith we have provided you. They wronged Us not, but they were wont to wrong themselves. 160 And remember when they were commanded, “Reside in this township and eat whatever you wish in it, and say ‘Sins are forgiven’ and enter the gate prostrating – We will forgive you your sins; We shall soon bestow more upon the virtuous.” 161 But those who were unjust among them changed it for a saying other than that which had been spoken to them; so We sent upon them a pestilence from heaven because they were unjust. 162
