“For many centuries, a prominent feature of the Muslim religious landscape has been the variety of spaces of gathering co-existing harmoniously with the masjid, which in itself has accommodated a range of diverse institutional spaces for educational, social and reflective purposes. Historically serving communities of different interpretations and spiritual affiliations, these spaces have retained their cultural nomenclatures and characteristics, from ribat and zawiyya to khanaqa and jamatkhana. The congregational space incorporated within the Ismaili Centre belongs to the historic category of jamatkhana, an institutional category that also serves a number of sister Sunni and Shia communities, in their respective contexts, in many parts of the world. Here, it will be space reserved for traditions and practices specific to the Shia Ismaili tariqah of Islam. ” – Mawlana Hazar Imam, at the Foundation Ceremony of the Ismaili Centre, Dubai, 13 December 2003.
Always doubt honesty of the people who their gathering and ceremonies are held in an unmarked building! If there's nothing wrong going on, why would they hide themselves behind break walls? ! Have you seen any church, synagogue, Buddhist temple, gurdwara or mosque like that? !
