The Islamic Society of Greater Houston (ISGH) says it is “the largest Islamic Society in North America” because it operates 19 separate mosques, 6 full-time schools, 4 clinics and 2 funeral homes.
The ISGH constitution and bylaws state that every due-paying member automatically becomes a member of the Islamic Society of North America, which receives a portion of their dues. The policy manual states that ISGH’s title is held by the North American Islamic Trust. Both of these organization are linked to the Muslim Brotherhood.
