Investments in UK-listed shariah-compliant shares, that meet Islamic law, have outperformed the FTSE 100 during the past year, as well as in the previous three and five years, in spite of the fact that shariah-compliant shares are limited in number.

The Dow Jones UK Islamic Index produced total returns of 15.2 per cent during the past 12 months - more than twice those of the FTSE 100, according to Trowers & Hamlins, the law firm.
