Islamic finance: 'A mortgage consistent with my faith'

As the World Islamic Economic Forum draws to a close, the BBC hears from one Muslim man who explains how he wants a mortgage "consistent with my faith".
The forum caters to the millions of Muslims who seek an alternative to traditional loans by charging fees or rent on property instead of interest.
Islamic finance already accounts for one in every $100 in the global banking system and London is just one of the financial centres hoping to cash in on that trend, as Nora Fakim reports.
