The Holy Quran 18:74 — Surah Al-Kahf
Arabic text
فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَـٰمًا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًۢ بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْـًٔا نُّكْرًا
Translation
So they proceeded (further on foot) until they met a boy whom he (Khidr) killed. (Shocked at the gruesome act, Moosa عليه الصلاة والسلام burst out, "Have you killed an innocent soul that has not taken another soul (and therefore does not deserve to be killed in retaliation)? You have now surely perpetrated (done) a great wrong (not reasonable)."
Tafsir (excerpt) — Tafsir Usmani
The killing of the boy: near a certain village some boys were playing. He seized one of them, the most handsome and clever, and killed him, and [they] went on. In some reports his name is given as Jaysur. Was this boy of age or not? Some say that he had reached puberty, and that the word ghulam (boy, youth) does not indicate that one has not come of age.
