And when he reached his full strength and was ripe, We gave him wisdom and knowledge. Thus do We reward the good. 14 He came to the city when the people were in a care-free mood, and saw two men quarrelling, one belonging to his community, the other to his enemies. 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 He said: "My Lord! Verily, I have wronged myself, so forgive me." Then He forgave him. Verily, He is the Oft-Forgiving, the Most Merciful. 16 He said: my Lord! whereas Thou hast favoured me, I shall nevermore be a supporter of the culprits. 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 Moses decided to lay his violent hands on the man belonging to the enemy, he cried out: "Moses, do you intend to kill me as you killed a person yesterday?" You simply want to live in the land as a tyrant, and do not wish to set things right." 19 A man came running from the farthest part of the city saying, "Moses, people are planning to kill you. I sincerely advise you to leave the city. 20 So Moses departed from the city, fearful and vigilant, and prayed, "My Lord, save me from these unjust people." 21
