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 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 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 18 Then, when he decided to lay hold of the man who was an enemy to both of them, that man said: "O Moses! Is it thy intention to slay me as thou slewest a man yesterday? Thy intention is none other than to become a powerful violent man in the land, and not to be one who sets 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 Moses departed from the city, fearful and vigilant, and prayed, "My Lord, save me from these unjust people." 21
