And when he reached his maturity and full strength, We gave him wisdom and knowledge; and this is how We reward the virtuous. 14 And he entered the city at a time of unawareness of its people, and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing, verily, he is a plain misleading enemy." 15 He said: My Lord! surely I have done harm to myself, so do Thou protect me. So He protected him; surely He is the Forgiving, the Merciful. 16 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 17 And morning found him in the city, fearing, vigilant, when behold! he who had appealed to him the day before cried out to him for help. Moses said unto him: Lo! thou art indeed a mere hothead. 18 And when Moses decided to lay his violent hands on the man belonging to the enemy, he cried out: "Moses, do you intend to kill me as you killed a person yesterday?" You simply want to live in the land as a tyrant, and do not wish to set things right." 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 departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
