External Shariah auditing in Islamic banks: what do internal auditors think?

PurposeThis study aims to investigate the pragmatic issues on the radical call for the establishment of an external Shariah auditor (ESA) in the governance framework of Islamic banks (IBs).Design/methodology/approachFrom 11 well-established Malaysian IBs, 16 internal auditors were interviewed to provide an in-depth understanding on how ESA can provide greater assurance to stakeholders in Malaysian IBs.FindingsThis study reported mixed acceptance from internal auditors on the proposed additional governance layer to be undertaken by the ESA. Generally, internal auditors reluctantly agreed that Shariah auditing by the ESA would enhance the quality of Shariah assurance but maintain several practical concerns regarding lack of guidelines on Shariah auditing, the additional cost to be borne by IBs and the possible tensions between the ESA and Shariah board (SB) amid the diverse Shariah interpretations available for experts in the field.Practical implicationsThe critical point on the manifestation of an ESA in the contemporary IB practice brought by this study highlights the need for regulation and policy promulgation that embrace a comprehensive approach to Shariah audit process within the religio-ethical dogma of Islamic banking and the pragmatic approach to banking.Originality/valueThis study provides evidence on the expected role and competency of an ESA and explores the implications produced by its implementation in Malaysian IBs. This study also clarifies how IBs should delineate the role of Shariah assurance from SB to ESA.
