When he had grown up to full maturity, We gave him wisdom and knowledge. Thus do We recompense 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 Then he prayed: "My Lord! I have indeed inflicted wrong on myself, so do forgive me," wherefore Allah forgave him for He is Ever Forgiving, Most Merciful. 16 He said: "My Lord! For that with which You have favoured me, I will never more be a helper for the Mujrimun (criminals, disobedient to Allah, polytheists, sinners, etc.)!" 17 He remained in the city but very afraid and cautious. Suddenly the person who asked him for help the previous day asked him for help again. Moses said, "You are certainly a mischievous person". 18 When he wanted to catch the one who was an enemy to them both, the man said, "Moses, do you want to kill me just as you killed a man yesterday? You only want to become a tyrant in the land; you do not want to set things right." 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 left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
