When he reached full age, and was firmly established (in life), We bestowed on him wisdom and knowledge: for 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 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! because Thou hast bestowed a favor on me, I shall never be a backer of the guilty. 17 And in the morning he was in the city fearing and looking about, when lo! he who had asked his succour yesterday was crying out unto him. Musa said: verily thou art a seducer manifest. 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 went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
