Now when [Moses] reached full manhood and had become mature [of mind]. We bestowed upon him the ability to judge [between right and wrong] as well as [innate] knowledge: for thus do We reward the doers of good. 14 And he entered the city, at a time when its people were unheeding, and found there two men fighting; the one was of his own party, and the other was of his enemies. Then the one that was of his party cried to him to aid him against the other that was of his enemies; so Moses struck him, and despatched him, and said, 'This is of Satan's doing; he is surely an enemy misleading, manifest.' 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 the favor You bestowed upon me, I will never be an assistant to the criminals." 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 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 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 So he left, fearful and vigilant, saying: 'My Lord, save me from the harmdoing nation' 21
