When Moses reached full manhood and maturity, We bestowed upon him wisdom and knowledge: this is how We reward those who do 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 He said: "My Lord! Verily, I have wronged myself, so forgive me." Then He forgave him. Verily, He is the Oft-Forgiving, the Most Merciful. 16 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 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 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 left the city in fear, waiting to see what happens; he said, “My Lord! Rescue me from the unjust people.” 21
