PurposeThe purpose of this study is to investigate the effect of financial performance (FP) and governance on the accounting and auditing organization for Islamic financial institutions (AAOIFI) disclosure for the Islamic banks.Design/methodology/approachThe authors used the generalized least squares (GLS) estimation for 47 MENASA (Middle East, North Africa and Southeast Asia) Islamic banks (IBs) between 2012 and 2019. In this regression, disclosure is the endogenous variable. The performance and governance measures are the explanatory parameters. The authors use bank's size, leverage and age for control parameters. The robustness of results is verified via generalized method of moments (GMM) estimation method.FindingsThe findings indicate that performance measurement has weak effects on AAOIFI disclosure. Only the net interest margin (NIM) measure has a significant positive impact. The return of assets (ROA) and the return on equity (ROE) have a significant negative impact. Furthermore, all Shariah Governance measures have significant effects. Finally, the findings of this study support the governance's positive contribution to the disclosure in IBs.Practical implicationsThrough including the whole issues allied to AAOIFI and their impacts on the banks' value, this study provides a significant summary for IBs, policymakers, regulators, AAOIFI and connected authorities across countries. In addition, the findings linked powers between jurisdictions with recommendations on growing the present AAOIFI practices.Originality/valueThis paper offers an original contribution to the accounting professionals and stakeholders who investigate the relationship between disclosure, performance and governance. It is considered as a basis for future studies in the simultaneous relation between these variables. It is crucial for accounting professionals, researchers and stakeholders interesting in the financial disclosure (FD) in IBs.
