The Story of killing the Boy Allah tells:فَانطَلَقَاThen they both proceeded,means, after the first incident,حَتَّى إِذَا لَقِيَا غُلَمًا فَقَتَلَهُtill they met a boy, and he (Khidr) killed him.It has been stated previously that this boy was playing with other boys in one of the towns, and that Al-Khidr deliberately singled him out. He was the finest and most handsome of them all, and Al-Khidr killed him. When Musa, peace be upon him, saw that he denounced him even more fervently than in the first case, and said hastily:قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًHe (Musa) said:Have you killed an innocent person,meaning, a young person who had not yet committed any sin or done anything wrong, yet you killed himبِغَيْرِ نَفْسٍwithout Nafs,with no reason for killing him.لَّقَدْ جِيْتَ شَيْيًا نُّكْرًاVerily, you have committed a thing Nukr!meaning, something that is clearly evil.قَالَ أَلَمْ أَقُل لَّكَ إِنَّكَ لَن تَسْتَطِيعَ مَعِي صَبْرًا
