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 as You have favored me, I will never be a helper to the wrongdoer' 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 Then as he was about to lay hands on the one who was their common enemy, he cried out: "O Moses, do you want to kill me as you killed that person yesterday? You only want to be a tyrant in the land and no peacemaker." 19 And a man came running from the outer part of the city; he said, “O Moosa! Indeed the court members are considering killing you, therefore go away – I surely am your well-wisher.” 20 So he escaped from thence, fearing, vigilant. He said: My Lord! Deliver me from the wrongdoing folk. 21
