The Islamic Banking is evolving to become an important part of the banking systems as the growth rate of this banking over the last few years has been very large recently. The Islamic banking activities are consistent with the Islamic law, which recognized as fiqh mualamat, the Islamic rules on transactions, which governed by the rules of Shariah (Calyon Credit Agricole CIB, 2008).

Whist, Islamic banking system which exercising the non-interest bearing loan that will results banks have to allocate proportionately more protective capital of approximately 100%, which is double from the usual rate to absorb losses (Keefe, 2004).
Although Islamic banking is fast growing, but the size of these banks are usually relatively small....
