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 And of the people of Musa there is a community guiding others by the truth and judging thereby. 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 when it was said to them: "Live in this land and eat of its produce wheresoever you like, and ask for remission of your sins, but pass through the gates with submission (and not pride), We shall forgive your trespasses, and give to those who are righteous abundance," 161 the transgressors among them substituted something else for the word they had been given. So We sent them a punishment from heaven for their wrongdoing. 162
