Well, it's the wave of the future. From [1] AKI, with thanks to Sr. Soph:

Singapore, 5 Jan. (AKI) - The Singapore stock exchange is developing a separate set of indices for stocks compliant with with Shariah or Islamic Law - which excludeds stocks of companies dealing in such Koran prohibited activities as the sale of pork or pork-based products, liquor, and those involving gambling. The first index of the series, the FTSE-SGX Asia Shariah 100 Index, is expected to be launched next month. The Singapore exchange is hoping that such a move will provide more opportunities for Islamic investors to invest in Asian markets....

All the stocks in the index are expected to go through a screening process, using Yassar Research's proprietary screening methodology, which is backed by a panel of Islamic scholars.
