The Mosque

The English word "mosque" denotes a Muslim house of worship. The word evolved from the Arabic term masjid, which means "place of prostration." During prayer, Muslims briefly kneel and touch their foreheads to the ground as a sign of submission (literally, Islam) to the will of God.
The Origin of the Mosque
The Prophet Muhammad's original house in Medina (in present-day Saudi Arabia) is thought to be the first mosque and probably served as a model for early mosque architecture. It was a mud-brick structure with living quarters on one side of an enclosed rectangular courtyard. Since Muhammad's followers would gather at his home for prayer, the side of the courtyard facing the qibla, or the direction of prayer, included a porch covered by palm branches, which offered shelter from the hot desert sun. Most early mosques, as well as the majority of later mosques in Arab lands, follow this general layout (see fig. 4).
Essential Architectural Elements of a Mosque
The essential architectural elements include:

• The qibla is the direction Muslims face when praying toward the Ka'ba in Mecca. The qibla wall is the wall in a mosque that faces Mecca.
• The mihrab is a niche in the qibla wall indicating the direction of Mecca; because of its importance, it is usually the most ornate part of a mosque, highly decorated and often embellished with inscriptions from the Qur'an (see image 4).
• The minbar is a pulpit in the form of a staircase on which the prayer leader (imam) stands when delivering a sermon after Friday prayer. The pulpit is usually situated to the right of the mihrab and is often made of elaborately carved wood or stone (fig. 3).
• A minaret is a tall tower attached or adjacent to a mosque. It is designed so the call to prayer, issued from mosques five times a day, can be heard loud and clear throughout a town or city. Alternatively, the call may be made from the roof or entrance, and is now often projected with the aid of microphones and speakers. The minaret is also a visual symbol of the presence of Islam. (See the six minarets of the Sultan Ahmed Mosque, fig. 6.).
• Most mosque courtyards (sahn) contain a public fountain, where believers can perform ablutions, the ritual washing of the hands, feet, and face required before prayer. In the arid lands of Arabia, water is revered as a gift from God, and fountains also have symbolic meaning, alluding to the four rivers of Paradise mentioned in the Qur'an.

The Role of the Mosque
Mosques reflect the size and needs of individual Muslim communities, as their members all worship together on Fridays. Historically mosques have been at the center of education and intellectual life.
Inscriptions from the Qur'an adorn the interiors and exteriors of mosques, establishing a strong link between scripture and the place of prayer. Mosque decoration almost never includes human or animal forms, which are seen as potentially idolatrous. Instead, geometric, floral, vegetal, and calligraphic designs adorn mosques, symbolically recalling the promise of Paradise.
Mosques around the World
Mosques throughout the Islamic world use diverse building materials and reflect different regional traditions and styles. Despite variations in size and design, the special place mosques hold in Muslim communities remains universal.
