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 Among the people of Moses are some whose guidance and Judgment are based on the Truth. 159 We divided them into twelve tribes, each a nation. And when his people demanded drink, We revealed to Moses: 'Strike the rock with your staff' Thereupon twelve springs gushed from the rock and each tribe knew its drinking place. We caused the clouds to cast their shadow over them, and sent down for them manna and quails, saying: 'Eat of the good things We have provided for you' Indeed, they did Us no wrong, but they wronged themselves. 160 And when it was said to them, 'Dwell in this township and eat of it wherever you will; and say, Unburdening; and enter in at the gate, prostrating; We will forgive you your transgressions, and increase 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
