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, 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 He prayed, "Forgive me Lord, for I have sinned against my soul." God forgave him; for He is the Forgiving One, the Merciful. 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 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 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 And a man came running from the outer part of the city; he said, “O Moosa! Indeed the court members are considering killing you, therefore go away – I surely am your well-wisher.” 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
