The dual structure of Malaysia’s capital market offers investors both sharīʿah-compliant and conventional investment options, creating expectations for Islamic accountability among sharīʿah-compliant public listed companies (PLCs). Drawing on institutional theory, this study contends that stakeholders’ pressures act as a form of coercion, shaping corporate behaviour in relation to zakat disclosure, a fundamental component of Islamic social responsibility. \ Using a comprehensive Zakat disclosure index (ZDI), this study assesses the extent of zakat disclosure among 160 sharīʿah-compliant PLCs for financial year 2023. The findings reveal that disclosure levels remain critically low, with 85.2% of firms reporting no zakat information and the majority scoring below 50%, reflecting weak institutional pressures and limited internal governance mechanisms. Sectoral differences are pronounced, with the financial services sector demonstrating stronger compliance due to higher regulatory expectations, while most other sectors lag significantly. Overall, the results highlight a substantial sap between sharīʿah-compliant status and substantive Islamic accountability, suggesting the need to institutionalise zakat disclosure as part of transparent, responsible, and socially aligned corporate practice.
