Masjid Omar ibn al-Khattab opened in 1994 and is situated adjacent to the campus of the University of Southern California (USC). The mosque is a part of the Omar Ibn Al Khattab Foundation. The Omar Foundation has sponsored and hosted Muslim–Jewish dialogues and is represented on the Los Angeles Unified School District’s Human Relations Council and the Advisory Board of Days of Dialogue.
A sizable amount of funding for the mosques construction came from the Kingdom of Saudi Arabia.
The Omar Ibn Al-Khattab Foundation is a board member of The Muslim American Homeland Security Congress (MAHSC), alongside multiple Muslim Brotherhood-affiliated organizations.
