Qatar International Islamic Bank

QIIB has come a long way since it was established as a full-service bank committed to Sharia principles at the beginning of 1991. It now has 15 branches and offices to its name and 70 ATMs across the Gulf state.

The lender is a majority shareholder in Islamic Bank of Britain, owning 91 per cent of the bank and recently lending it $15.5 million to help narrow its losses for 2012.
