Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided." 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 And recall what time it was said unto them: dwell in yonder town and eat plentifully therefrom anything ye list, and say: fergiveness, and enter the gate bowing; and We will forgive you your trespasses: anon We will increase unto the well-doers. 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
