In terms of form or architecture of the Ismaili jamatkhanas, again as with other Muslim spaces of gathering, there is no single ‘monolithic’ type or required norm. Rather, the forms vary depending on the cultural context, geography, materials available, technology and, of course, varieties of functions required. Reflecting this last criterion (of function), the larger jamatkhanas contain not only prayer halls, but also meeting areas, classrooms, libraries, recreation and social spaces, etc.
To conclude, beginning with the revelation of the Holy Qur’an and the historical experiences of Muslims over 1400 years (cumulative traditions), the devotional life of Muslims has consisted of a rich variety of expressions, forms, interpretations and spaces. As a result, a pluriform rather than uniform culture has been characteristic of the reality of Muslim societies throughout history. Moreover, this cultural pluralism, rather than being a weakness, remains a source of strength and inspiration for millions of Muslims around the world.
