And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 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 Forgive me, my Lord, for I have wronged myself' and so He forgave him; for He is indeed the Forgiving, the Most Merciful. 16 He said: My Lord! Forasmuch as Thou hast favoured me, I will nevermore 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 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 19 And there came a man from the farthest part of the city, running; he said: O Musa! the chiefs are taking counsel together concerning thee, that they might slay thee; wherefore go forth thou, verily I am unto thee of the admonishers. 20 So he escaped from thence, fearing, vigilant. He said: My Lord! Deliver me from the wrongdoing folk. 21
