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 [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 said: My Lord! Lo! I have wronged my soul, so forgive me. Then He forgave him. Lo! He is the Forgiving, 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 So he became afraid, looking about in the city (waiting as to what will be the result of his crime of killing), when behold, the man who had sought his help the day before, called for his help (again). Musa (Moses) said to him: "Verily, you are a plain misleader!" 18 When he wanted to catch the one who was an enemy to them both, the man said, "Moses, do you want to kill me just as you killed a man yesterday? You only want to become a tyrant in the land; you do not want to set things right." 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 it, fearful and anticipating [apprehension]. He said, "My Lord, save me from the wrongdoing people." 21
