<![CDATA[The period of the Umayyad Dynasty (661–750 AD) is often considered a period of minimal scientific contribution, even though this era was a critical phase in the formation of Islamic scientific epistemology. This research aims to reconstruct and analyze how science was conceptualized and practiced in that era, focusing on the dynamics of the integration of the three pillars of knowledge: ‘Aql (intellect), Revelation, and Inheritance of civilization. This study is important to fill in the gaps in the understanding of the epistemological evolution of Islamic science before it reached its peak in the Abbasid era. The research uses a qualitative design with a historical-philosophical approach. Data is collected through literature studies and documentation, then analyzed by philosophical interpretation and content analysis. The results of the study show that the interaction of the three sources of knowledge in the Umayyad era was dynamic, pragmatic, and driven by state needs. This integration manifested itself in the fields of astronomy, architecture, medicine, and theology, creating a selective and directed initial synthesis. This study concludes that the Umayyad era was not a period of scientific vacuum, but rather a foundational period that laid down an epistemological framework, intellectual infrastructure, and integrative awareness between revelation, reason, and the legacy of civilization. The implication is a reassessment of the significance of the Umayyad era in the grand narrative of Islamic science history, with a theoretical contribution in enriching the philosophical map of Islamic science and a historical contribution in uncovering critical phases of transmission and adaptation.]]>
