Say: 'O mankind, I am the Messenger of God to you all, of Him to whom belongs the kingdom of the heavens and of the earth. There is no god but He. He gives life, and makes to die. Believe then in God, and in His Messenger, the Prophet of the common folk, who believes in God and His words, and follow him; haply so you will be guided.' 158 And of Moses' folk there is a community who lead with truth and establish justice therewith. 159 We divided them into twelve tribes or nations. We directed Moses by inspiration, when his (thirsty) people asked him for water: "Strike the rock with thy staff": out of it there gushed forth twelve springs: Each group knew its own place for water. We gave them the shade of clouds, and sent down to them manna and quails, (saying): "Eat of the good things We have provided for you": (but they rebelled); to Us they did no harm, but they harmed their own souls. 160 And (remember) when it was said to them: "Dwell in this town (Jerusalem) and eat therefrom wherever you wish, and say, '(O Allah) forgive our sins'; and enter the gate prostrate (bowing with humility). We shall forgive you your wrong-doings. We shall increase (the reward) for the good-doers." 161 The wicked among them changed and perverted the word We had spoken to a word unpronounced; so We sent from heaven retribution on them for all their wickedness. 162
