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 of carelessness of its folk, and he found therein two men fighting, one of his own caste, and the other of his enemies; and he who was of his caste asked him for help against him who was of his enemies. So Moses struck him with his fist and killed him. He said: This is of the devil's doing. Lo! he is an enemy, a mere misleader. 15 Forgive me, my Lord, for I have wronged myself' and so He forgave him; for He is indeed the Forgiving, the Most Merciful. 16 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 17 The next morning, when he was walking in the city, apprehensive, and watchful, and the man who had sought his help the day before cried out to him again for help. Moses said to him, "You are clearly a misguided man." 18 But when he would have assaulted the man who was an enemy to them both, the man said, 'Moses, dost thou' desire to slay me, even as thou slewest a living 'soul yesterday? Thou only desirest to be a tyrant in the land; thou desirest not to be of them that put things right.' 19 And a man came running from the remotest part of the city. He said: O Musa! surely the chiefs are consulting together to slay you, therefore depart (at once); surely I am of those who wish well to you. 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
