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 [one day] he entered the city at a time when [most of] its people were [resting in their houses,] unaware of what was going on [in the streets]; and there he encountered two men fighting with one another - one of his own people, and the other of his enemies. And the one who belonged to his own people cried out to him for help against him who was of his enemies - whereupon Moses struck him down with his fist, and [thus] brought about his end. [But then] he said [to himself]: "This is of Satan's doing! Verily, he is an open foe, leading [man] astray!" 15 He prayed: "O my Lord! I have indeed wronged my soul! Do Thou then forgive me!" So (Allah) forgave him: for He is the Oft-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 he became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." 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 There came a man running from the other part of the city. "O Moses," he said, "the chiefs are deliberating to kill you. Go away from the city. I wish you well." 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
