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 went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 He said, “My Lord! I have indeed wronged my soul* therefore forgive me” – He therefore forgave him; indeed only He is the Oft Forgiving, the Most Merciful. (* By getting angry.) 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 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 came a man from the furthest part of the city, running; he said, 'Moses, the Council are conspiring to slay thee. Depart; I am one of thy sincere advisers.' 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
