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 Yet there is a group among the people of Moses who guide with truth and act justly in accordance with it. 159 We divided them up into twelve tribes, each a whole community, and We revealed Our will to Moses, when his people asked for water, saying, "Strike the rock with your staff." Twelve springs gushed from it and each tribe knew its drinking place. We caused the clouds to draw their shadow over them and sent down for them manna and quails, saying, "Eat the good things We have given you." They did not wrong Us; rather it was themselves they wronged. 160 When it was said to them: 'Dwell in this village, and eat of whatever you please; and say, "Unburdening" and enter the gate prostrating, We will forgive you your sins and increase the gooddoers' 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
