Jamatkhana or Jamat Khana (from Persian: جماعت خانه, literally "congregational place") is an amalgamation derived from the Arabic word jama‘a (gathering) and the Persian word khana (house, place). It is a term used by some Muslim communities around the world, particularly sufi ones, to a place of gathering.[1] Among some communities of Muslims, the term is often used interchangeably with the Arabic word musallah (a place of worship that has not been formally sanctified as a masjid [2] or is a place that is being temporarily used as a place of worship by a Muslim). The Nizārī Ismā'īlī community uses the term Jama'at Khana to denote their places of worship.[3]
