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 Of the people of Moses there is a nation who guide by the truth, and by it act with justice. 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 [mention, O Muhammad], when it was said to them, "Dwell in this city and eat from it wherever you will and say, 'Relieve us of our burdens,' and enter the gate bowing humbly; We will [then] forgive you your sins. We will increase the doers of good [in goodness and reward]." 161 But the transgressors among them changed the word from that which had been given them so we sent on them a plague from heaven. For that they repeatedly transgressed. 162
