And when he reached his full strength and was ripe, We gave him wisdom and knowledge. Thus do We reward the good. 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 said, 'My Lord, I have wronged myself. Forgive me!' So God forgave him, for He is the All-forgiving, the All-compassionate. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of 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 But when he would have assaulted the man who was an enemy to them both, the man said, 'Moses, dost thou' desire to slay me, even as thou slewest a living 'soul yesterday? Thou only desirest to be a tyrant in the land; thou desirest not to be of them that put things right.' 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 went forth from thence fearing, looking about. He said: my Lord! deliver me from the wrong-doing people. 21
