And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge.

He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 (Moses) said, "Lord, I have wronged myself. Forgive me!" The Lord forgave him; He is All-forgiving and All-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 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?

I am one of your well-wishers." 20 So he left, fearful and vigilant, saying: 'My Lord, save me from the harmdoing nation' 21
