Difference between Islamic banks and conventional banks

Islamic banks have Shariah supervisory bodies that oversee their affairs (transactions) and are held accountable for their practices before Allah and man. These banks do not set a specific percentage for the capital, but put percentage on the profit made.

As for interest based banks, they do not have any shariah supervisory boards and they usually fix a particular percentage on the capital, for example 10% which may be higher or lower than that.
