And when he attained his full strength and became firm, We vouchsafed unto him wisdom and knowledge; and thus We reward the well-doers. 14 He entered the city without the knowledge of its inhabitants and found two men fighting each other. One was his follower and the other his enemy. His follower asked him for help. Moses struck his enemy to death, but later said, "It was the work of satan; he is the sworn enemy of the human being and wants to mislead him". 15 He said: My Lord! surely I have done harm to myself, so do Thou protect me. So He protected him; surely He is the Forgiving, the Merciful. 16 He said, "Lord, in appreciation for Your favor to me I shall never support the criminals". 17 And morning found him in the city, fearing, vigilant, when behold! he who had appealed to him the day before cried out to him for help. Moses said unto him: Lo! thou art indeed a mere hothead. 18 So when Moosa wished to apprehend the man who was an enemy to them both, he said, “O Moosa! Do you wish to kill me the way you killed a man yesterday? You only wish to become a strict ruler in the land, and not to make reform.” 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 So he went forth therefrom, fearing, awaiting, (and) he said: My Lord! deliver me from the unjust people. 21
