Say: 'O mankind, I am the Messenger of Allah to you all. His is the kingdom in the heavens and the earth. There is no god except He. He revives and causes to die. Therefore, believe in Allah and His Messenger, the Unlettered Prophet, who believes in Allah and His Words. Follow him in order that you are guided.' 158 And among the people of Moses is a community which guides by truth and by it establishes justice. 159 We divided them into twelve (different) tribes. When his people asked for water, We said to Moses: "Strike the rock with your staff;" and behold, twelve springs of water gushed forth, so that each of the tribes had a place of its own to drink; and We made the clouds spread shade over them and sent for them manna and quails (and said): "Eat of the good things We have provided for you." But (by disobeying) they did not harm Us, they harmed 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 But those among them who were bent on wrongdoing substituted another saying for that which they had been given: and so We let loose against them a plague from heaven in requital of all their evil doings. 162
