Islamic finance has been discussed on this board in the past so as a public service I thought I would point out what appears to be a really good book on the subject (I have not finished it yet!).

A Primer on Islamic Finance
Shanmugan, B. and Zahari, R.
The Research Foundation of CFA Institute
copyright 2009

ISBN 978-1-034667-24-8

Hope this might be helpful.
