Mosques are buildings that serve as the main place of worship for Muslims and its could be any house or open area of prayer.
           In the Islamic religion, the mosques serve social and politic needs as well as religious once.  The first Mosque was the courtyard of Prophet Mohammed's own house in Madina (In Present Day Saudi Arabia) in the Arabian Peninsula, which was the model for the past Islamic architecture.  The Prophet's home was a simple structure, made of raw brick, which opened on an enclosed courtyard where people came to hear him.
          "Qibla wall" is the wall in the direction toward which Muslims turn five times a day when they are praying.  "qibla" is in the direction to " alKabba "in  Makka city. In the beginning of alhijara the direction of "alqiblla" was Jerusalem city.
         "Mihrab " is the prayer niche in the " qibla" wall, and its vary in size and type and its usually decorated. Next to "mihrab" is "alminbar" where the Friday sermon is preached.
        "Alminarat " is the towers behind the mosques and its usually higher than the mosque building.  The use of "Minarat" began with mosque of Kairouan in the 8th century in Tunisia. 
        In the earliest mosques, al "Muezzin or crier" was the person who call the people for the pray, and its was directly from the roof of the mosque.  Belal Bin Rabah was the first crier in the Islamic religion.
