Xizr
No, the Quran mentions a 'servant of Allah' in Surah Al-Kahf (18:65) who meets Moses, but the name Khizr is derived from Hadith and Islamic tradition.
He symbolizes the eternal spiritual guide (murshid), divine knowledge (ilm ladunni), and the green vitality of the soul nourished by divine presence.
It is extremely rare as a given name but is well-known as a spiritual title and symbol in Persian Sufi poetry and folklore.
Green represents life, resurrection, and the freshness of divine mercy, linking Xizr to the ever-living spiritual realm.
Traditionally masculine due to the figure's male identity in Islamic tradition, though the qualities are universal.
