Arabic hadith text
وَعَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّمَا سُمِّيَ الْخَضِرُ لِأَنَّهُ جَلَسَ عَلَى فَرْوَةٍ بَيْضَاءَ فَإِذَا هِيَ تَهْتَزُّ من خَلْفِه خضراء» . رَوَاهُ البُخَارِيّ
Translation
Abu Hurayrah reported that the Prophet said: ‘Al-Khidr was given his name because he sat on a bare patch of white ground, and it turned green behind him.’ Al-Bukhari transmitted it.
