An important Shii theological college in the central Iranian city of Qom, adjacent to the shrine of Fatimah Masumah (d. 816), sister of the eighth Shii imam, Ali ibn Musa al-Rid (d. 818). It was initially built during the Safavid period (1501–1722) and was later named after a noted Shii theologian, Muhammad ibn Murtaza Kashani (d. 1679), known as Mulla Mohsen Faiz, who studied and later taught there. With the influx of Shii scholars following the collapse of the Ottoman Empire, Faiziyyah was revived and expanded under the intellectual leadership and administrative supervision of Ayatollah Abd al-Karim Haeri Yazdi (d. 1937). Since then it has been a major center of Shii learning. In 1963 Faiziah was the scene of confrontations between state security forces and demonstrators, leading ultimately to Ayatollah Khomeini's arrest and eventually his exile from the country.
