And when he reached his maturity and full strength, We gave him wisdom and knowledge; and this is how We reward the virtuous. 14 He entered the city without the knowledge of its inhabitants and found two men fighting each other. One was his follower and the other his enemy. His follower asked him for help. Moses struck his enemy to death, but later said, "It was the work of satan; he is the sworn enemy of the human being and wants to mislead him". 15 He said, "My Lord, indeed I have wronged myself, so forgive me," and He forgave him. Indeed, He is the Forgiving, the Merciful. 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 became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." 18 And when he would have fallen upon the man who was an enemy unto them both, he said: O Moses! Wouldst thou kill me as thou didst kill a person yesterday. Thou wouldst be nothing but a tyrant in the land, thou wouldst not be of the reformers. 19 And there came a man, running, from the furthest end of the City. He said: "O Moses! the Chiefs are taking counsel together about thee, to slay thee: so get thee away, for I do give thee sincere advice." 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
