David S. Powers’ book, originally a doctoral dissertation submitted to Princeton University, is a welcome addition to the already growing corpus of studies revising Joseph Schacht’s thesis that Islamic law did not exist during the lifetime of the Prophet. This is, however, not the central theme of the book. Powers contends that the Islamic law of inheritance is not identical to the system of inheritance revealed to Prophet Muhammad and that the Muslim community is not in possession of the original reading and understanding of several Qur’anic verses and Prophetic hadith.

The second part proceeds by looking at socio-economic developments in the early period and contends that people in power manipulated the Qur‘anic ...
