And when he was fully grown and in the perfection of his strength, We gave him judgment and knowledge; even so do We recompense the good-doers. 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, forasmuch as Thou hast blessed me, I will never be a partisan of the sinners.' 17 So he saw the morning in the city, looking about, in a state of fear, when behold, the man who had, the day before, sought his help called aloud for his help (again). Moses said to him: "Thou art truly, it is clear, a quarrelsome fellow!" 18 And when he would have fallen upon the man who was an enemy unto them both, he said: O Moses! Wouldst thou kill me as thou didst kill a person yesterday. Thou wouldst be nothing but a tyrant in the land, thou wouldst not be of the reformers. 19 A man came running from the farthest part of the city saying, "Moses, people are planning to kill you. I sincerely advise you to leave the city. 20 So he escaped from there, looking about in a state of fear. He said: "My Lord! Save me from the people who are Zalimun (polytheists and wrong-doers)!" 21
