And when he reached his maturity and full strength, We gave him wisdom and knowledge; and this is how We reward the virtuous. 14 He entered the city unnoticed by its people, and there he encountered two men fighting with one another -- one of his own people and the other one of his enemies. The one who belonged to his own people cried out to him for help against his foe -- whereupon Moses struck him down with his fist, thereby causing his death. Moses said, "This is Satan's doing; he is an open foe, leading man astray." 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 as You have favored me, I will never be a helper to the wrongdoer' 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 when he decided to seize the man who was an enemy to both of them, the man said: "O Musa (Moses)! Is it your intention to kill me as you killed a man yesterday? Your aim is nothing but to become a tyrant in the land, and not to be one of those who do right." 19 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 Soon after hearing this Moses departed in a state of fear, looking around as one in apprehension and prayed: "My Lord, deliver me from these unjust people." 21
