When Moses reached full manhood and maturity, We bestowed upon him wisdom and knowledge: this is how We reward those who do good. 14 And he entered the city unnoticed by the people and found two men fighting, one was of his own party, and the other of his enemies. The one of his party appealed for his help against his enemy, Moses struck and killed him, and said: 'This is the work of satan, he is surely a clear, misleading enemy. 15 [And] he prayed: O my Sustainer! Verily, I have sinned against myself! Grant me, then, Thy forgiveness!" And He forgave him - for, verily, He alone is truly forgiving, a dispenser of grace. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 And morning found him in the city, fearing, vigilant, when behold! he who had appealed to him the day before cried out to him for help. Moses said unto him: Lo! thou art indeed a mere hothead. 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 a man came from the uttermost part of the city, running. He said: O Moses! Lo! the chiefs take counsel against thee to slay thee; therefor escape. Lo! I am of those who give thee good advice. 20 So he left the city, fearful and hesitant, (and) prayed: "O Lord, deliver me from these wicked people." 21
