Requirements for Mashriqu'l-Adhkar sites

A site for a future Mashriqu'l-Adhkar can be as small as 8,000 square metres in area if a larger property would be too expensive. It should, if possible, be situated within the city designated or, if this is not feasible, within 25 kilometres from the city.
