Sheikh Sharaf ad-Din ibn al-Hasan

Shaykh Sharaf ad-Dīn ibn al-Hasan, known also by the Yazidi name Şêx Sherfeddin, was a descendant of Umayyad Caliph Marwan ibn al-Hakam. He was the son and religious heir of al-Hasan ibn ‘Adī and thus head of the ‘Adawiyya Ṣūfī Order. He died in battle against the Mongols in 1258 and was succeeded by his uncle, Fakhr ad-Dīn ibn ‘Adī.
The Sherfedin sanctuary is considered to be one of the oldest and most important Yazidi sites.
