Definition the Principles and Laws of Islamic Urbanism based on Unchangeable Rules

Unchangeable rulings can be the basis for preparing principles and laws in Islamic urban planning. This approach, centered on God's fixed decrees, has inherent characteristics, immutability over time, comprehensiveness, and the ability to be applied in all aspects of Islamic urban planning. Failure to pay attention to the fixed rules in urban planning in the era of Hasir has led to the emergence of many inefficient plans that have had negative consequences on various aspects of human life. Therefore, this research aims to explain the principles and foundations of the city and Islamic urban planning based on the fixed rulings, which was carried out with the research method of content analysis of texts and logical reasoning, and methods of library and document study. The findings of the research show that fixed rules in Islamic thought are a transcendental, efficient and appropriate approach in recognizing, explaining and analyzing various subjects, including urban studies and the Islamic city. According to this attitude, every knowledge consists of two natural and valid propositions, and the validity of the valid propositions depends on the compatibility and compliance of the natural propositions. The fixed rules are the laws of the Sharia that are established for human beings based on human nature. Credit laws are variable laws that are created according to the needs and expediency of the society in different periods. Islamic realism can be used in line with a critical view of urban planning and design and monitoring of urban developments. Therefore, from a fixed point of view, an Islamic city is a city where Muslims, relying on Islamic fixed affairs, strive to achieve true happiness. Islamic city and urban planning is based on Islamic realism, planning, design and management of cities with the focus of fixed divine decrees. These rulings should be the basis for the validity of city and urban development laws and regulations in various physical-spatial, social, economic, cultural, environmental, managerial and legal fields.
