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 went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 He prayed, "Forgive me Lord, for I have sinned against my soul." God forgave him; for He is the Forgiving One, the Merciful. 16 (Moses) said: "O Lord, as You have been gracious to me I will never aid the guilty." 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 Then as he was about to lay hands on the one who was their common enemy, he cried out: "O Moses, do you want to kill me as you killed that person yesterday? You only want to be a tyrant in the land and no peacemaker." 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 escaped from thence, fearing, vigilant. He said: My Lord! Deliver me from the wrongdoing folk. 21
