Zayd ibn Ali
Zayd was a revered and respected member of the "Bayt" (Household) of Muhammad. Scholars, Saints, Sufis and Imams alike, all spoke of him in respectful terms. When the ascetic Umayyad Caliph Umar ibn Abd al-Aziz was the Governor of Madinah during the reign of Al-Walid and Suleiman, he was an associate of Zayd ibn Ali. Zayd continued to correspond and advise him when he became the Khalifah.
