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 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: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 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 And when he sought to seize him who was an enemy unto them both, he said: O Musa wouldst thou slay me as thou didst slay a person yesterday? Thou seekest only to be a tyrant in the land, and thou seekest not to be of the reconcilers. 19 And there came a man from the farthest part of the city, running; he said: O Musa! the chiefs are taking counsel together concerning thee, that they might slay thee; wherefore go forth thou, verily I am unto thee of the admonishers. 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
