Sultan Choudhury, managing director of Islamic Bank of Britain, discussed findings from a poll of more than 300 investors by IBB, which showed one-third of respondents were non-Muslim. Some 66 per cent of those surveyed believed sharia finance was appropriate in a modern western society. A similar number (60 per cent) said sharia finance was relevant to all faiths, while more than half (58 per cent) said they considered Islamic finance to be an ethical system. IBB also reported 81 per cent of its customers said they were likely to use sharia-compliant finance again. This first piece of research will shape how the retail market for Islamic finance evolves, he added.
