Say: "O men, I am verily the apostle of God to you all. His whose kingdom extends over the heavens and the earth. There is no god but He, the giver of life and death. So believe in God and the messenger, the gentile Prophet, sent by Him, who believes in God and His messages. Obey him; you may haply be guided aright." 158 Yet among the people of Moses there was a nation who preached the truth and acted justly. 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 When they were told, "Settle down in the town and eat wherever you wish in it, and pray for forgiveness and enter the gate in humility: We shall forgive you your sins and shall bestow further favours upon those who do good," 161 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
