<p>Urban integration is a crucial criterion for evaluating the quality of city development. Social segregation during physical and spatial transformation is undesirable, separating different social classes within neighborhoods. This phenomenon can create significant contradictions between wealthier and lower socio-economic neighborhoods, ultimately threatening city spatial integration. Spatial justice in urban areas does not necessarily mean equalizing different regions. Instead, it involves systematically organizing the spatial needs of each neighborhood, respecting their diversity. Differences between neighborhoods based on location should not lead to a sense of superiority; residents’ connection to their neighborhood should be the determining factor. This paper examines the concept of balance in urban integration from an Islamic perspective. It analyzes the quality of life and typologies of various areas within the Tehran metropolis (112 districts) to measure physical spatial separation. The research methodology involves explaining specific theoretical concepts derived from Islamic sources and determining quantitative indicators to assess spatial segregation. The analysis of urban integration utilizes geo-referential analysis and cartographic models for all areas in Tehran. The study employs 50 quantitative indicators to evaluate the actions and policies of city administration regarding the organization of urban regions over the past two decades. This assessment helps determine whether the changes in Tehran, as the capital of an Islamic country, have leaned towards urban balance and dynamism or toward spatial segregation. The findings indicate that the extensive spatial changes in Tehran over the last two decades have resulted in spatial discontinuity rather than spatial integration.</p>
