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 And he entered the city, at a time when its people were unheeding, and found there two men fighting; the one was of his own party, and the other was of his enemies. Then the one that was of his party cried to him to aid him against the other that was of his enemies; so Moses struck him, and despatched him, and said, 'This is of Satan's doing; he is surely an enemy misleading, manifest.' 15 "O Lord," he prayed, "I have done wrong, forgive me." And God forgave him. Verily He is forgiving and kind. 16 (Moses) said: "O Lord, as You have been gracious to me I will never aid the guilty." 17 And he was in the city, fearing, awaiting, when lo! he who had asked his assistance the day before was crying out to him for aid. Musa said to him: You are most surely one erring manifestly. 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 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
