﴿ فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَٰمًۭا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًۭا زَكِيَّةًۢ بِغَيْرِ نَفْسٍۢ لَّقَدْ جِئْتَ شَيْـًۭٔا نُّكْرًۭا ﴾

“And so the two went on, till, when they met a young man, [the sage] slew him -(whereupon Moses] exclaimed: "Hast thou slain an innocent human being without [his having taken] another man's life? Indeed, thou hast done a terrible thing!"”

(So the twain journeyed on till, when they met a lad) between two townships, (he slew him) Khidr killed him. ((Moses) said: What! Hast thou) O Khidr (slain an innocent soul who hath slain no man? Verily thou hast done a horrid thing) you have committed a horrendous, evil act.
