Theory and Practice of Modern Islamic Finance seeks to contribute to the existing body of work in the area of Islamic finance through examining the extent of divergence in practice of Islamic financing from the traditional Sharìah in the Australian context. The author makes a discursive analysis of the regulation of Islamic finance in Australia in terms of (a) the financing instruments used, (b) certainty of transactions between participants in the system, and (c) institutional risk management of Islamic financial institutions. The work's objectives are two-fold: (a) to analytically study the extent to which Islamic Financial Services Providers (IFSPs) of Australia differ from the traditional Sharìah in their current practices of Islamic legal financial system by their use of different financial products and techniques, and (b) to create awareness and transparency about the various products and instruments used by IFSPs of Australia.
