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 there is a group among the people of Moses who guide with truth and act justly in accordance with it. 159 And We divided them into twelve tribes (as distinct) nations. We directed Musa (Moses) by inspiration, when his people asked him for water, (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs: each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm 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 So the unjust among them changed the words, contrary to what they had been commanded – consequently We sent down upon them a punishment from the sky – the recompense of their injustice. 162
