And when he reached his maturity and full strength, We gave him wisdom and knowledge; and this is how We reward the virtuous. 14 Once he entered the city at a time when its people were heedless, and he encountered two men fighting, one of whom belonged to his own people and the other to his foes. Now the man belonging to Moses' own people cried out to him for help against the man from the foes, and Moses struck him with his fist and finished him. Moses said: "This is an act of Satan. Surely he is an enemy who openly misleads." 15 (Moses) said, "Lord, I have wronged myself. Forgive me!" The Lord forgave him; He is All-forgiving and All-merciful. 16 Thereupon Moses vowed: "My Lord, because of the favour that You have done me I shall never support the guilty." 17 So he saw the morning in the city, looking about, in a state of fear, when behold, the man who had, the day before, sought his help called aloud for his help (again). Moses said to him: "Thou art truly, it is clear, a quarrelsome fellow!" 18 Then when he decided to seize the man who was an enemy to both of them, the man said: "O Musa (Moses)! Is it your intention to kill me as you killed a man yesterday? Your aim is nothing but to become a tyrant in the land, and not to be one of those who do right." 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
