Shaykh ‘Adī ibn Musāfir al-Umawī (Kurdish: Şêx Adî, died 1162), reputedly a descendant of Umayyad Caliph Marwan ibn al-Hakam, is born in the 1070s in the Beqaa Valley of present-day Lebanon.

Adi is said to have been born in the village of Bait Far, near Baalbek, where the house of his birth was in and is still the place of pious pilgrimage.

The Yazidi consider him an Avatar of Tawûsê Melek, the "Peacock Angel".

His tomb at Lalish, Iraq is a focal point of Yazidi pilgrimage.
