Today, the world is confronted with serious environmental challenges and a shortage of green spaces. In Iran, many urban green spaces and parks have been designed and constructed without proper consideration of the local culture and climate, deviating significantly from the fundamental principles of traditional Persian garden design. At almost every scale, there is both a lack of green space and widespread unprincipled planning and construction, often incompatible with the climatic and cultural characteristics of society. This highlights the need to examine relevant jurisprudential and ethical principles in order to identify existing deficiencies and offer solutions. A review of contemporary parks in Tabriz reveals that none of them fully comply with the jurisprudential rules and ethical principles considered in this study. Since modern residential complexes—unlike traditional houses—are generally disconnected from natural green areas, access to public parks and gardens has gained critical importance. Designing and developing green spaces in accordance with Islamic regulations and ethical considerations offers significant potential. In other words, the functional use of green space can and should be guided by jurisprudential and moral principles. Emphasizing Persian garden design principles, incorporating natural landscapes, enhancing functionality, and following ethical guidelines can play an essential role in improving the quality and sustainability of urban green spaces.
