This paper places the articles in this special issue in the contexts of Islamic economics and finance research. It highlights the foundations of Islamic economics, which are in practice manifested in Islamic finance. Then, the paper brings up three key issues in Islamic finance today – the Islamicity of Islamic banking, real contributions of Islamic finance, and Islamic finance in the present monetary framework. While there are some promising theoretical and empirical findings pointing to positive contributions of Islamic finance, there is still a need for Islamic finance to distinguish itself from the conventional finance and to further demonstrate its real effect.
