And when he attained his full strength and became firm, We vouchsafed unto him wisdom and knowledge; and thus We reward the well-doers. 14 He came to the city when the people were in a care-free mood, and saw two men quarrelling, one belonging to his community, the other to his enemies. The man who belonged to his community appealed for help against the one who belonged to the enemies. Moses struck him a blow with his fist and finished him off. "This is of Satan's doing," he said. "He is certainly an enemy and a corrupter." 15 He said: my Lord! verily I have wronged my soul, so wherefore forgive me. So He forgave him. Verily He! He is the Forgiving, the Owner of Mercy. 16 He said, “My Lord! The way You have bestowed favour upon me, so never will I be a supporter of the guilty.” 17 And he was in the city, fearing, awaiting, when lo! he who had asked his assistance the day before was crying out to him for aid. Musa said to him: You are most surely one erring manifestly. 18 And when he wanted to strike the one who was an enemy to both of them, he said, "O Moses, do you intend to kill me as you killed someone yesterday? You only want to be a tyrant in the land and do not want to be of the amenders." 19 And a man came from the farthest end of the city, running. He said, "O Moses, indeed the eminent ones are conferring over you [intending] to kill you, so leave [the city]; indeed, I am to you of the sincere advisors." 20 So he left the city, fearful and hesitant, (and) prayed: "O Lord, deliver me from these wicked people." 21
