The oldest extant book on the genealogy of the Safavid family is Safvat as-safa and was written by Ibn Bazzaz in 1350, a disciple of Sheikh Sadr-al-Din Safavi, the son of Sheikh Safi ad-din Ardabili. According to Ibn Bazzaz, the Sheikh was a descendant of a Kurdish man named Firooz Shah Zarrin Kolah who was from Sanjar, southeast of Diyarbakir. The male lineage of the Safavid family given by the oldest manuscript of the Safvat as-Safa is: "Sheykh Safi al-Din Abul-Fatah Ishaaq the son of Al-Sheykh Amin al-din Jebrail the son of al-Saaleh Qutb al-Din Abu Bakr the son of Salaah al-Din Rashid the son of Muhammad al-Hafiz al-Kalaam Allah the son of ‘Avaad the son of Birooz al-Kurdi al-Sanjari." Later Safavid Kings themselves claimed to be Seyyeds, family descendants of the Islamic prophet Muhammad.
