Auditing is an examination and verification of a company's financial and accounting records and supporting documents by a professional, such as a Certified Public Accountant. According to AlBaraka, Islamic bank is an institution that mobilizes financial resources and invests that money in an attempt to achieve pre-determined islamically - acceptable social and financial objectives. Both mobilization and investment of money should be conducted in accordance with the principles of Islamic Sha’riah whereas according to Ustaz Hj Zaharuddin (2007) stated that conventional bank operates based on debtor-creditor relationships.For example, it is between depositors (creditor) and bank (debtor); and borrowers (debtor) and the bank (creditor).

Conventional bank maximize profit by charging interest to customers.
