The man who belonged to his community appealed for help against the one who belonged to the enemies. Moses struck him a blow with his fist and finished him off. "This is of Satan's doing," he said. "He is certainly an enemy and a corrupter." 15 [And] he prayed: O my Sustainer! Verily, I have sinned against myself! Grant me, then, Thy forgiveness!" And He forgave him - for, verily, He alone is truly forgiving, a dispenser of grace. 16 Thereupon Moses vowed: "My Lord, because of the favour that You have done me I shall never support the guilty." 17 The next morning he proceeded to the city in fear and looking around as one apprehensive of danger when all of a sudden, the man who had sought his help the day before again called out to him for his help. Moses said to him: "Clearly, you are a very misguided fellow." 18 So when Moosa wished to apprehend the man who was an enemy to them both, he said, “O Moosa! Do you wish to kill me the way you killed a man yesterday? You only wish to become a strict ruler in the land, and not to make reform.” 19 And a man came running from the remotest part of the city. He said: O Musa! surely the chiefs are consulting together to slay you, therefore depart (at once); surely I am of those who wish well to you. 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
