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 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 Then he prayed: "My Lord! I have indeed inflicted wrong on myself, so do forgive me," wherefore Allah forgave him for He is Ever Forgiving, Most 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 So he became afraid, looking about in the city (waiting as to what will be the result of his crime of killing), when behold, the man who had sought his help the day before, called for his help (again). Musa (Moses) said to him: "Verily, you are a plain misleader!" 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 And [then and there] a man came running from the farthermost end of the city, and said: "O Moses! Behold, the great ones [of the kingdom] are deliberating upon thy case with a view to killing thee! Begone, then: verily, I am of those who wish thee well!" 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
