Say: 'O mankind, I am the Messenger of Allah to you all. His is the kingdom in the heavens and the earth. There is no god except He. He revives and causes to die. Therefore, believe in Allah and His Messenger, the Unlettered Prophet, who believes in Allah and His Words. Follow him in order that you are guided.' 158 Yet there is a group among the people of Moses who guide with truth and act justly in accordance with it. 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) when it was said to them: "Dwell in this town (Jerusalem) and eat therefrom wherever you wish, and say, '(O Allah) forgive our sins'; and enter the gate prostrate (bowing with humility). We shall forgive you your wrong-doings. We shall increase (the reward) for the good-doers." 161 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
