Say thou: O mankind! verily I am the apostle of Allah unto you all - of Him whose is the dominion of the heavens and the earth. No god is there but He; He giveth life and causeth to die. Believe then in Allah and His prophet, the unlettered prophet, who believeth in Allah and His words, and follow him that haply ye 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 descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging 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 Then the evildoers of them substituted a saying other than that which had been said to them; so We sent down upon them wrath out of heaven for their evildoing. 162
