Abstract
<title>Abstract</title> <p>This study develops a Quranic framework for environmental sustainability in Islamic economics through the principle of al-Mīzān, presented in the Quran as a normative order regulating relationships among humankind, nature, and resources. Using an integrated mixed quantitative–qualitative methodology, the research identifies 315 verses related to four core Qur’anic constructs—al-Mīzān (balance), fasād (corruption), iṣlāḥ (reform), and istikhlāf (stewardship)—and traces their chronological development across the Meccan and Medinan periods. The coded sample shows that 72% of the verses addressing balance and corruption belong to the Medinan phase, suggesting a historical shift from moral exhortation toward institutional guidance and from individual responsibility toward collective environmental governance. Building upon this evolution, the study introduces the concept of Maqāṣid-based Sustainability, which harmonizes the preservation of wealth (ḥifẓ al-māl) and the preservation of the environment (ḥifẓ al-bīʾa) as complementary objectives within the framework of maqāṣid al-sharīʿah (the higher objectives of Islamic law). The paper further proposes a practical model for Islamic environmental economics, grounded in three applied mechanisms: The Islamic Circular Economy – promoting responsible production and consumption. The Environmental Waqf (Endowment) – as a sustainable financing instrument. The Green Zakāt Fund – supporting ecological justice and renewable energy initiatives. By linking ethical accountability with contemporary sustainability goals, the Qur’anic principle of al-Mīzān offers a normative framework for rethinking the human–nature relationship in terms of stewardship, reform, and balanced coexistence rather than consumption and domination.</p>
