Shari’ah compliance in Islamic banking is necessary. However, achieving that requires certain additional operations and costs which may lead to Islamic banks incurring some additional costs which conventional banks simply avoid. This may make Islamic banks to become costlier than conventional banks and which will reflect in weak position in price competitiveness.
In Mudarabah, only the Rabb-ul-Maal bears all the financial losses as the sole financial investor. If an Islamic bank enters into a Mudarabah contract as a Rabb-ul-Maal, only the Islamic bank would have to bear all the losses. Disparity in payoffs if loss occurs in Mudarabah is one of the major reasons why Mudarabah is hardly used as a mode of finance in corporate financing.
