(mosque; pl. Masajid) Arabic derived from the root sa-ja-da, meaning ‘to prostrate’. In the early Islamic era, the word masjid meant a place of prayer which could be any clean spot on earth. The first masjid in Islam was built in Medina in 622 CE. The masjid is primarily a designated space for the offering of canonical ritual prayers by Muslim congregations. Besides its religious function, masjid is also used as the centre of community life which can serve social, political and educational roles. The architectural style of the masjid often reflects the style of the region and the period in which they were established. Important functionaries of the masjid are the prayer leader (Imam al-Masjid) and the person who calls to prayer (al-Mu’adhdhin).
