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 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 We divided them into twelve (different) tribes. When his people asked for water, We said to Moses: "Strike the rock with your staff;" and behold, twelve springs of water gushed forth, so that each of the tribes had a place of its own to drink; and We made the clouds spread shade over them and sent for them manna and quails (and said): "Eat of the good things We have provided for you." But (by disobeying) they did not harm Us, they harmed 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 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
