And when he attained his full strength and became firm, We vouchsafed unto him wisdom and knowledge; and thus We reward the well-doers. 14 And he entered the city at a time when its people were not watching: and he found there two men fighting,- one of his own religion, and the other, of his foes. Now the man of his own religion appealed to him against his foe, and Moses struck him with his fist and made an end of him. He said: "This is a work of Evil (Satan): for he is an enemy that manifestly misleads!" 15 He prayed, "Forgive me Lord, for I have sinned against my soul." God forgave him; for He is the Forgiving One, the Merciful. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 He remained in the city but very afraid and cautious. Suddenly the person who asked him for help the previous day asked him for help again. Moses said, "You are certainly a mischievous person". 18 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 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 Moses departed from the city, fearful and vigilant, and prayed, "My Lord, save me from these unjust people." 21
