By Abdur-Rahman Ibn Yusuf
Nowadays, in the west, many Islamic Centers being managed include, among other things, a prayer hall, musallā, or jamāt khāna. Some communities rent an industrial unit, a store front, a house, or an apartment in which members of the Muslim community gather to perform congregational prayer (and in many cases
social activities). Many communities actually have purchased property which they consider their masjid.
Which of the above can technically be considered a masjid, and what are the related rulings?
