The Islamic Foundation of Shaikh Ibn Taymiyyah preceded the mosque. It supervised its planning, design, etc., and now owns and operates the mosque (as well as that of two other Southern California mosques — Masjid al Salam in central Los Angeles, and
Islamic Center of Riverside, California — and supervises "Zamzam Schools" for "girls' education and the memorization of the Qur'an"). The foundation was established in 1980 (1400
AH). It began as the "Muslim Student House" in the western Los Angeles area. As the Muslim population and Saudi funding grew, a house was purchased in the same area for prayers, lectures and Dawa activities. The foundation is now located at 11004 Washington Boulevard, across Huron Ave from the Mosque. Named after the 14th century Islamic jurist,
Ibn Taymiyyah, the foundation is an Islamic
charity organization under US law, and as such is exempt from taxes, entitled to own property and practice religious, educational, informational and intellectual activities throughout the US. As of 2017 it reported revenues of $320,000 and five employees. The foundation's stated objectives include propagating Islam, unifying Muslims, building mosques, schools and colleges, holding conferences and publishing books. ==9/11 investigation==
