So believe in God and the messenger, the gentile Prophet, sent by Him, who believes in God and His messages. Obey him; you may haply be guided aright." 158 Of the people of Moses there is a section who guide and do justice in the light of truth. 159 And We cut them up into twelve tribes as communities. And We revealed unto Musa, when his people asked him for drink: Smite the rock with thy rod. Then gushed forth therefrom twelve springs: every people already knew their drinking-places. And We shaded them with thick clouds, and We sent down upon them the manna and the quails, saying: eat of the clean things wherewith We have provided you. And they wronged not Us, but themselves they were wont to wrong. 160 When they were told, "Settle down in this town, eat as you wish, seek forgiveness and enter the gate prostrating yourselves (in obedience to the Lord) and We will forgive you your sins and increase the reward of the righteous people, 161 the transgressors among them substituted something else for the word they had been given. So We sent them a punishment from heaven for their wrongdoing. 162
