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 He said: My Lord! surely I have done harm to myself, so do Thou protect me. So He protected him; surely He is the Forgiving, the Merciful. 16 He said, “My Lord! The way You have bestowed favour upon me, so never will I be a supporter 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 So when he desired to seize him who was an enemy to them both, he said: O Musa! do you intend to kill me as you killed a person yesterday? You desire nothing but that you should be a tyrant in the land, and you do not desire to be of those who act aright. 19 And a man came running from the remotest part of the city. He said: O Musa! surely the chiefs are consulting together to slay you, therefore depart (at once); surely I am of those who wish well to you. 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
