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 AMONG the folk of Moses there have been people who would guide [others] in the way of the truth and act justly in its light. 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 [mention, O Muhammad], when it was said to them, "Dwell in this city and eat from it wherever you will and say, 'Relieve us of our burdens,' and enter the gate bowing humbly; We will [then] forgive you your sins. We will increase the doers of good [in goodness and reward]." 161 The wicked amongst them changed what was said for other words. Therefore We sent down upon them from heaven a punishment for their evil doing. 162
