Although most of the largest mosques are located in major Islamic countries, many newly built mosques are also found in different countries around the world.

It is named for the grandson of Muhammad, Husayn ibn Ali, whose head is believed by Fatimid Shia/Dawoodi Bohra to be buried on the grounds of the mosque. The mosque, considered to be one of the holiest Islamic sites in Cairo was built on the cemetery of the Fatimid caliphs, a fact that was later discovered during the excavation.
