When Moses reached the age of full youth and grew to maturity, We bestowed upon him wisdom and knowledge. Thus do We reward those who do good. 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 myself, so forgive me." Then He forgave him. Verily, He is the Oft-Forgiving, the Most Merciful. 16 He said: My Lord! because Thou hast bestowed a favor on me, I shall never be a backer of the guilty. 17 So he was in the city at morning fearing, waiting to see what happens – thereupon he sighted the one who had appealed to him the day before, crying out to him for help; Moosa said to him, “Indeed you are clearly astray.” 18 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 19 Then came a man from the furthest part of the city, running; he said, 'Moses, the Council are conspiring to slay thee. Depart; I am one of thy sincere advisers.' 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
