With the vision of a leader, Imam Sayed Moustafa Al-Qazwini, along with the assistance of a few community members pioneered the establishment of the first mosque in Irvine, California, in addition to being the first mosque that follows the tradition of Ahlul-Bayt (the family of the holy Prophet Muhammad).

The Islamic Educational Center of Orange County (IECOC) opened its doors to the Muslim community of Orange County in September 1996 in a small rented building in Irvine, California. Its focal aim was to provide the teachings of the Holy Quran, the Sunnah of Prophet Muhammad (pbuh&hf), and Ahlul-Bayt (as) to the communities of Orange and Los Angeles Counties.

After two-short years, the IECOC community quickly outgrew its facility. With the assistance from Allah (swt), the community was able to raise funds to purchase a new building in Costa Mesa, California. The new location was inaugurated in the Holy month of Ramadan 1420/December 1999 and now serves the larger Orange and Los Angeles Counties.
