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 And of the people of Musa there is a community guiding others by the truth and judging thereby. 159 And We divided them into twelve tribes, forming them into communities. When his people asked Moses for water We directed him: 'Smite the rock with your rod.' Then twelve springs gushed forth from the rock and every people knew their drinking-places. And We caused thick clouds to provide them shade, and We sent down upon them manna and quails, saying: 'Eat of the clean things that We have provided you.' They wronged not Us, but it was themselves that they wronged. 160 And remember it was said to them: "Dwell in this town and eat therein as ye wish, but say the word of humility and enter the gate in a posture of humility: We shall forgive you your faults; We shall increase (the portion of) those who do good." 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
