The building of a masjid (the place where one prostrates oneself) institutes a specific sacralised space within the primary and essential sacrality of the universe as a whole; as the Prophet said, "The whole earth is a masjid" [Bukhari, Musilm]. Once built, the masjid becomes the axial space of the Muslim spiritual community in which it is situated, but it also expresses the reality of settlement, of acceptance of the hosting space, which is then turned into a space for oneself, a home. Indeed, the presence of the masjid reveals that a place has been adopted as home, and that the believing conscience is "at home" because the place of worship, a reminder of meaning, has been set up. The Prophet's repeated act is in itself a teaching: whatever the exile or journey, whatever the movement or departure, one must never lose sight of meaning and direction. Masjids tell of meaning, direction, and settlement.
