Islamic finance: Attractive for non-Muslims?

It is often claimed that Islamic finance is not only for Muslims, sending the message that the market potential of Islamic finance is far greater than just the global population of Muslims. However, Shari'ah compliance as the constitutive element of Islamic finance is in itself rather irrelevant for non?Muslims. It could be macro?systemic or micro?commercial or ethical implications of the observance of Islamic law which make it appealing to non?Muslims. If it is not 'systemic superiority' that will attract non?Muslims, then it could be the pricing of Islamic products or their quality that the customers see as individual benefit for themselves. The responsible investing movement is a great opportunity for Islamic finance, but also a great challenge at the same time.
