And when he reached his full strength and was ripe, We gave him wisdom and knowledge. Thus do We reward the 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 (Moses) said, "Lord, I have wronged myself. Forgive me!" The Lord forgave him; He is All-forgiving and All-merciful. 16 He said: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 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 And when Moses was about to seize he who was the enemy of both of them, he said: 'Moses, would you kill me as you killed a living soul yesterday? You desire only to be a tyrant in the land, and you do not want to be among the reformers' 19 A man came running from the far side of the city, and said, "Moses, the authorities are conspiring to kill you, so leave the city. I am one of your well-wishers." 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
