When Muslim Nomad Arabs were scattered around as a religious jihad from Arabian Peninsula at the beginning of the seventh century AD, they had nothing of their own except their new religion; they did not know much about architectural techniques, their cities were just piles of primary mud cottages and their villages were just squads of tents or straw huts. Their only place of worship was Kaaba in Mecca which had relationship with none of the art degrees of buildings. However, a few decades after this emigration, they began a movement with the help of the defeated nations and their inherent facilities which could be called “Urbanization and development movement”; such being the case, after a short period of time, they began to build cities such as Kufa, Basra, Wasit, Baghdad on east and Fustat and Ramallah on west. Relying on the historical sources and evidences, this study aims at answering the question of the factors for such an understanding by the nomad Arabs and its historical necessity.
