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 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 He said: my Lord! verily I have wronged my soul, so wherefore forgive me. So He forgave him. Verily He! He is the Forgiving, the Owner of Mercy. 16 He said: My Lord! Forasmuch as Thou hast favoured me, I will nevermore be a supporter of the guilty. 17 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 18 So when he desired to seize him who was an enemy to them both, he said: O Musa! do you intend to kill me as you killed a person yesterday? You desire nothing but that you should be a tyrant in the land, and you do not desire to be of those who act aright. 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 went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
