Say, "People, I am God's Messenger to you all, He has sovereignty over the heavens and the earth. There is no god but Him. He ordains life and death, so believe in God and His Messenger, the unlettered prophet who believes in God and His words. Follow him so that you may be rightly guided." 158 Among the people of Moses' there was a party who guided others in the way of the truth and established justice in its light. 159 And We divided them into twelve tribes, as separate groups; and when his people asked him for water, We revealed to Moosa, “Strike the rock with your staff”; so twelve springs gushed forth from it; each group recognised its drinking-place; and We made the clouds a canopy over them and sent down the Manna and the Salwa (birds) on them; “Eat of the good things we have provided you”; and they did not wrong Us in the least, but they used to wrong themselves. 160 And [remember] when you were told: "Dwell in this land and eat of its food as you may desire; but say, 'Remove Thou from us the burden of our sins,' and enter the gate humbly - [whereupon] We shall forgive you your sins [and] shall amply reward the doers of good." 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
