Is there such a thing as Islamic ETF's that you can invest in?

There are 3 traded on the London exchange sponcered by Barclays. Ishares MSCI Emerging Markets Islamic ticker ISEM, Ishares MSCI USA Islamic ticker ISUS, and Ishares MlSCI World Islamic ticker ISWD. The best way to buy any of these is to open an account with a broker that has access to the London exchange. Two are Interactive Brokers and ETrade. Good luck.
