And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of 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 Then he prayed: "My Lord! I have indeed inflicted wrong on myself, so do forgive me," wherefore Allah forgave him for He is Ever Forgiving, Most Merciful. 16 He said, "My Lord, for the favor You bestowed upon me, I will never be an assistant to the criminals." 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 he wanted to catch the one who was an enemy to them both, the man said, "Moses, do you want to kill me just as you killed a man yesterday? You only want to become a tyrant in the land; you do not want to set things right." 19 Then a man came running from the furthest part of the city, 'Moses' he said, 'the Assembly are plotting to kill you. Leave, for I am one of your sincere advisers' 20 So he went forth from thence fearing, looking about. He said: my Lord! deliver me from the wrong-doing people. 21
