وَعَنْ أُبَيِّ بْنِ كَعْبٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ الْغُلَامَ الَّذِي قَتَلَهُ الْخَضِرُ طُبِعَ كَافِرًا وَلَوْ عَاشَ لَأَرْهَقَ أَبَوَيْهِ طُغْيَانًا وَكُفْرًا» . مُتَّفَقٌ عَلَيْهِ

Ubayy b. Ka’b reported God’s messenger as saying, “The youth whom al-Khidr killed was given the nature of an infidel, and if he had lived, he would certainly have imposed on his parents insolence and unbelief[*].” *Cf. Quran, 28:80. (Bukhari and Muslim.)
