Surah Ar-rum has been widely discussed and researched by many researchers, which shows the intricacy of the Arabic language. This study explores the complexities of Surah Ar-Rum, with a specific focus on verse 41, to reveal its essence and examine its modern-day implications. This research seeks to bridge the gap between the spiritual wisdom contained in Quranic verse and its relevance to contemporary environmental issues, specifically the negative effects of oil spills on marine fish populations. The challenge lies in comprehending the deeper meaning of Surah Ar-Rum Verse 41, due to its intricate Arabic. This complication has hindered full comprehension of its intended message, potentially limiting its application in a variety of domains, including environmental awareness and conservation. To address this, the study employs the ADDIE model (Analyse, Design, Develop, Implement, and Evaluate) to gather relevant information on the topic. Three different exegesis (tafsir) sources are used to gain insight into the meaning of Surah Ar-Rum Verse 41. The study incorporates related references to improve understanding of the verse's relevance to contemporary environmental issues. It focuses on the effects of oil spills on marine ecosystems and fish populations. The research seeks to draw parallels between the metaphoric downfall described in the verse and the tangible ecological disruptions caused by oil pollution by pairing Quranic wisdom with scientific knowledge. Ultimately, this research aims to bridge the gap between spiritual insights from Surah Ar-Rum Verse 41 and the ecological challenges faced by marine environments. Through comprehensive tafsir analysis and integration with scientific findings, the study hopes to illuminate potential lessons that can be derived from this sacred text and applied to modern conservation efforts.
