It is known that the Islamic formative art was established on the basis of the countries' arts congested  by the Muslims or the countries subjected to them as the dessert nature of the peninsula at the Bedouins' moving from a place to another wouldn't help formative arts but in the far sites of the peninsula like "Menazerah" parallel to the "Sasani" and "Ghasani" states neighbors of the "Bezantian" state, the right of the peninsula's southern western corner where arts competed with these of their contemporaries of Persians and Romans existed.

      Yet the Arab conqueror didn't accept all he found of these arts as it were but he excluded what distend by religion and what doesn't suits its special taste,then he gathered what he chose of it and melt it in a spot after giving it his private taste which is the Arab writing , thus we can say that the Islamic art took its spiritual entity from the mid of the peninsula , while its substantial entity was formed in some other places in which art had power and life.    

     Maybe, the most prominent branches of Islamic art which was affected by the spiritual side, is architecture, to which the first Muslim's paid a great attention, therefore the religious architecture rapidly developed to cope with the Islamic civilization, Thus its shapes and methods were multiple according to its functions' multiplicity and changing .     

     The Islamic architecture started by building Mosques , schools,public drinking places, chapels and almshouses if we wanted to follow the development of Islamic architecture we will find the corner stone in it is "the Mosque".

Building the Mosque.

    The first thing prophet mohammed "may peace be upon him"- made when he immigrated to "Medina"- was building a Mosque for the Muslims in "Merbed El- Tamr" where his camel knelt down , it was simple and primitive, of 60x70 arms of sun- dried bricks a part of it was ceated with palm leaves while the other part left uncovered and the Mosque's pillars were of palm stock.   

The Muslims walked the same way in establishing "El-Basre" Mosque in the year 14th of "Hijra", " El- kufa" Mosque in year 17th Hijra, "Amr Ben El- Aas" also followed this way in building his mosque in "El-Fustat"in year 21st Hijra whose space - at the establishment- was 50x30 arms , of sun- dried bricks and pillars of palm stock dominated by simplicity.

    Mosques in "El- kufa" , "El- Basra" and Egypt were empty of hollow pulpits ,minarets alike Mosque of prophet Mohammed " may peace be upon him".   

   Muslims in the first Islamic age were limited in using the word mosque for the places of adoration.In language, Mosque is the place in which Bowing takes place , and when space of the Islamic state expended and the Muslims increased , by those who entered Islam of these countries congested by Muslims- the Mosques multiplied in some countries as names released at places of adoration, thus it becomes a Mosque and Gama.Gama is a description of Mosque because it is the place in which people gather and named "the big Mosque".        

   Therefore , the word "Gama" had a political significance in the "Omawian" state's age , known by "Gama", the mosque in which the caliph or his deputies who heads the Muslims in Friday's prayers, i.e the word "Gama" is released on the state's official Mosque that was known as "El- Gama Mosque".
