Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright. 158 Yet among the people of Moses there was a nation who preached the truth and acted justly. 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 [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 of them who did wrong changed the word which had been told them for another saying, and We sent down upon them wrath from heaven for their wrongdoing. 162
