Khidr
The Quran describes the 'wise servant' in Surah Al-Kahf (18:65-82) but does not name him Khidr; the name comes from Hadith and Islamic tradition.
The name derives from Arabic 'khudra' (green), symbolizing eternal youth, living knowledge, and connection to paradise.
Yes, Somali Muslims use the form Khadir or Xadiir, particularly within Sufi orders like the Qadiriyya.
Khidr represents the archetypal spiritual guide (murshid) who possesses ilm ladunni (divine knowledge), appearing in the works of Rumi and Hafez.
Islamic tradition generally regards him as a saint (wali) or angelic figure granted immortality to serve God's servants, though some traditions elevate him to prophethood.
