And when he reached his full strength and was ripe, We gave him wisdom and knowledge. Thus do We reward the good. 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 [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 (Moses) said: "O Lord, as You have been gracious to me I will never aid 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 But then as soon as he was about to lay violent hands on the man who was their [common] enemy, the latter exclaimed: "O Moses, dost thou intend to slay me as thou didst slay another man yesterday? Thy sole aim is to become a tyrant in this land, for thou dost not care to be of those who would set things to rights!" 19 There came a man running from the other part of the city. "O Moses," he said, "the chiefs are deliberating to kill you. Go away from the city. I wish you well." 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
