Now when [Moses] reached full manhood and had become mature [of mind]. We bestowed upon him the ability to judge [between right and wrong] as well as [innate] knowledge: for thus do We reward the doers of good. 14 He came to the city when the people were in a care-free mood, and saw two men quarrelling, one belonging to his community, the other to his enemies. The man who belonged to his community appealed for help against the one who belonged to the enemies. Moses struck him a blow with his fist and finished him off. "This is of Satan's doing," he said. "He is certainly an enemy and a corrupter." 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, for the favor You bestowed upon me, I will never be an assistant to the criminals." 17 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 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 farthest part of the city saying, "Moses, people are planning to kill you. I sincerely advise you to leave the city. 20 So he left the city, fearful and hesitant, (and) prayed: "O Lord, deliver me from these wicked people." 21
