This paper undertakes a systematic appraisal of the ethical environmental principles embedded in the Glorious Qur’an and examines their resonance with, and relevance to, the findings and demands of contemporary environmental science. Drawing upon classical Qur’anic exegesis, juristic reasoning, and prophetic tradition alongside modern ecological literature, the study demonstrates that Islam's environmental ethic is neither incidental nor peripheral but constitutes a foundational dimension of the faith itself. The Qur’an articulates a coherent philosophy of human stewardship (khilafah), the sanctity of the natural order (mizan), the prohibition of corruption and excess (fasad), and the imperative of moderation (wasat), all of which find direct correspondence in the most pressing environmental challenges of the twenty-first century, including climate change, deforestation, water scarcity, pollution, and the erosion of biodiversity. The paper concludes with ten concrete findings and ten actionable recommendations intended to guide both policy and practice in Muslimmajority societies and beyond.
