A mosque (/mɒsk/; from Arabic: مسجد‎ masjid) is a place of worship for followers of Islam.

There are strict and detailed requirements in Sunni fiqh for a place of worship to be considered a mosque, with places that do not meet these requirements regarded as musallas. There are stringent restrictions on the uses of the area formally demarcated as the mosque (which is often a small portion of the larger complex), and, in the Islamic Sharia law, after an area is formally designated as a mosque, it remains so until the Last Day.

Many mosques have elaborate domes, minarets, and prayer halls, in varying styles of architecture. Mosques originated on the Arabian Peninsula, but are now found in all inhabited continents. The mosque serves as a place where Muslims can come together for salat (صلاة ṣalāt, meaning "prayer") as well as a center for information, education, and dispute settlement. The imam leads the congregation in prayer.

Etymology

The word entered English from a French word that probably derived from Italian moschea, a variant of Italian moscheta, from either Middle Armenian մզկիթ (mzkit‘) or Medieval Greek μασγίδιον (masgídion) or Spanish mezquita, from the Arabic مسجد masjid meaning "place of worship" or "prostration in prayer", either from Nabataean masg^ĕdhā́ or from Arabic سجد sajada meaning "to bow down in prayer", probably ultimately from Aramaic s^ĕghēdh.
