The realization of justice is one of the foundational and complex themes in Islamic political thought. The problem this research addresses is explaining the mechanisms effective in realizing complete justice in the Islamic utopia. Due to its deep connection with religious beliefs, leaving this question unanswered can create grounds for doctrinal doubts and the emergence of ambiguities regarding the Islamic utopia. Adopting a descriptive-analytical approach and relying on library-based sources, this research explores both the theoretical and practical dimensions of realizing justice in the Islamic utopia. The findings indicate that the realization of justice in such a society requires an integration of both infrastructural and superstructural mechanisms. nfrastructural mechanisms, such as the development of rationality, faith, spirituality, epistemology, and culture, alongside superstructural mechanisms, such as intelligent power and abundance of blessings, play a pivotal role in achieving justice. The study further reveals that the primary reason for the lack of justice during the early Islamic period and the era of occultation lies in absence of infrastructural mechanisms. It concludes that the concurrent application of both types of mechanisms may contribute to the realization of relative justice in contemporary societies.
