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 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 Forgive me, my Lord, for I have wronged myself' and so He forgave him; for He is indeed the Forgiving, the Most Merciful. 16 He said: 'My Lord as You have favored me, I will never be a helper to the wrongdoer' 17 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 18 Then as he was about to lay hands on the one who was their common enemy, he cried out: "O Moses, do you want to kill me as you killed that person yesterday? You only want to be a tyrant in the land and no peacemaker." 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 departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
