Islamic civilization represents one of the most important civilization achievements phases that enriched human movement on earth, the Islamic architecture and urbanism as its physical container and one of its tributaries occupies a privileged position among the various urban and architectural styles and patterns known to human civilization across time and space. The Islamic architectural heritage patterns spread through various Islamic eras from Jakarta-Indonesia to Tangier-Morocco and from Ghana- Africa to Ferghana-Asia, in a unique urban planning compositions and variations of architectural forms. And in spite of the multiplicity of Islamic eras and its differentiation and multi-cultural aspects, it provided an integrated urban model (methodology, theory and legislation) reflected honestly the personality and characteristics of the Muslim community and the goals and purposes of the cultural model doctrine, law and ethics, which was behind the creative physical movement. The contemporary Muslim planner and architect finds himself in front of a civilized/urban dilemma, one hand, he stands impressed by the heritage of the Islamic Urban model and its artistic,aesthetic,engineering and constructive creativity. On the other he stands bewildered in front of the contemporary western urban model and its planning and architectural methodologies,theoriesand legislations,building technologies,methods and materials,which cause dramatic urban and cultural changes threaten the sustainability of the Islamic communities and its human and natural resources andfortunes.  And it stands on the other hand,unable to formulating an urban theory for architecture and planning, be an intellectually springboard and a source of inspiration filling the gap between past and present, and connecting the intellectual and creative discontinuation in the Islamic urban thought and contribute in constructingthe Islamic contemporary urban model (methodology, theory and legislation). The  research problem revolves around the absence of purposes of Islamic philosophy and thought  from the formation of  the awareness,conscience and thinkingof the contemporary Muslim architectand planner,or in another way the absence of  the architectural theory, which represents the Islamic intellectual springboard which catalyst the creative design and planning processes, the way it reflected upon his architectural and planning  production no longer express the contemporary Islamic society.And then the research aims to deduct a theory for contemporary Islamic urbanism, originates from the induction of the Architectural Heritage variables and the jurisprudenceof the Islamic Cultural model constants, and provides a contemporary intellectually paradigm obtained from a trial to understand the mysteries and contents of the Islamic planning and architectural formations based on a framework of Knowledge of values and purposes of Islamic law (MQASSED ASHAREEAH). The research based on the historical descriptive methodology of the origins and evolution of urban Islamic heritage across different ages, and on the inductive analytical methodology for eclectic range of urban architectural and planning to figure out the architectural and planning principals of her and the secrets of its formations and creative results, and then use deductive approach to detect and extract the goals and objectives of urban potential that can be that constitute the theory underlying the urban contemporary architecture contemporary Muslim and planned to resolve the problems and challenges of globalization and to contribute to the formulation of the features of a the better world;environment,community and urbanism.
