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 (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 when it was said to them: Reside in this town and eat from it wherever you wish, and say, Put down from us our heavy burdens: and enter the gate making obeisance, We will forgive you your wrongs: We will give more to those who do good (to others). 161 Then those of them who did wrong changed the word that had been told them for another, whereupon We sent upon them a scourge from the heaven for they were wont to transgress. 162
