And when he was fully grown and in the perfection of his strength, We gave him judgment and knowledge; even so do We recompense the good-doers. 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 [And] he prayed: O my Sustainer! Verily, I have sinned against myself! Grant me, then, Thy forgiveness!" And He forgave him - for, verily, He alone is truly forgiving, a dispenser of grace. 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 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 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 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 departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
