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 nations; and We revealed to Musa when his people asked him for water: Strike the rock with your staff, so outnowed from it twelve springs; each tribe knew its drinking place; and We made the clouds to give shade over them and We sent to them manna and quails: Eat of the good things We have given you. And they did not do Us any harm, but they did injustice to their own souls. 160 And recall what time it was said unto them: dwell in yonder town and eat plentifully therefrom anything ye list, and say: fergiveness, and enter the gate bowing; and We will forgive you your trespasses: anon We will increase unto the well-doers. 161 The wicked amongst them changed what was said for other words. Therefore We sent down upon them from heaven a punishment for their evil doing. 162
