And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 14 And he entered the city at a time of carelessness of its folk, and he found therein two men fighting, one of his own caste, and the other of his enemies; and he who was of his caste asked him for help against him who was of his enemies. So Moses struck him with his fist and killed him. He said: This is of the devil's doing. Lo! he is an enemy, a mere misleader. 15 He said: My Lord! Lo! I have wronged my soul, so forgive me. Then He forgave him. Lo! He is the Forgiving, the Merciful. 16 He said: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 17 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 18 And when he would have fallen upon the man who was an enemy unto them both, he said: O Moses! Wouldst thou kill me as thou didst kill a person yesterday. Thou wouldst be nothing but a tyrant in the land, thou wouldst not be of the reformers. 19 And a man came running from the remotest part of the city. He said: O Musa! surely the chiefs are consulting together to slay you, therefore depart (at once); surely I am of those who wish well to you. 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
