Say, [O Muhammad], "O mankind, indeed I am the Messenger of Allah to you all, [from Him] to whom belongs the dominion of the heavens and the earth. There is no deity except Him; He gives life and causes death." So believe in Allah and His Messenger, the unlettered prophet, who believes in Allah and His words, and follow him that you may be guided. 158 Of the people of Moses there is a nation who guide by the truth, and by it act with justice. 159 And We cut them up into twelve tribes, nations. And We revealed to Moses, when his people asked him for water: 'Strike with thy staff the rock'; and there gushed forth from it twelve fountains all the people knew now their drinking-place. And We outspread the cloud to overshadow them, and We sent down manna and quails upon them: 'Eat of the good things wherewith We have supplied you.' And they worked no wrong upon Us, but themselves they wronged. 160 And when it was said to them: Reside in this town and eat from it wherever you wish, and say, Put down from us our heavy burdens: and enter the gate making obeisance, We will forgive you your wrongs: We will give more to those who do good (to others). 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
