Purpose: This study examines the relationship between ESG practices and maqashid-oriented financial performance within a Tawhid String Relationship, addressing inconsistencies in prior findings by incorporating regulatory context and ethical sustainability disclosure. Methodology/approach: Using panel data from 37 energy sector firms listed on the IDX 2020–2024, with Moderated Regression Analysis to analyze the effects of Islamic governance, environmental accountability, and sustainable resource management on maqashid oriented-financial performance, with ethical sustainability disclosure as a moderating variable and PROPER as a contextual differentiator. Findings: The results indicate that ESG practices do not uniformly affect financial performance. Islamic governance and environmental accountability show context-dependent effects, while sustainability resource management demonstrates a strong positive impact, particularly in firms without PROPER. Ethical sustainability disclosure exhibits a dual moderating role, strengthening certain relationships in less regulated firms but weakening others due to cost and compliance pressures. Practical and Theoritical contribution/Originality: This study contributes by positioning ESG within TSR as a value-driven system aligned with maqashid objectives and highlights the need for strategic integration beyond disclosure. Research Limitation: This study is limited by its sectoral focus, observation period, and reliance on proxy-based ESG measurements, suggesting opportunities for broader and deeper future research.
