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 of unawareness of the inhabitants thereof, and he found therein two men fighting, one being of his own party, and the other of his enemies. And he who was of his party, called him for help against him who was of his enemies. So Musa struck him with his fist, and put an end of him. He said: this is of the work of the Satan, verily he is an enemy, a misleader manifest. 15 He prayed: "O my Lord! I have indeed wronged my soul! Do Thou then forgive me!" So (Allah) forgave him: for He is the Oft-Forgiving, Most Merciful. 16 He said, "My Lord, for the favor You bestowed upon me, I will never be an assistant to the criminals." 17 And next morning he found himself in the city, looking fearfully about him, when lo! the one who had sought his help the day before [once again] cried out to him [for help whereupon] Moses said unto him: "Behold, thou art indeed, most clearly, deeply in the wrong! 18 And when he wanted to strike the one who was an enemy to both of them, he said, "O Moses, do you intend to kill me as you killed someone yesterday? You only want to be a tyrant in the land and do not want to be of the amenders." 19 A man came running from the far side of the city, and said, "Moses, the authorities are conspiring to kill you, so leave the city. I am one of your well-wishers." 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
