: The article investigates the earliest appearance of a group of words which are identified in the literature as the shahāda but are rarely defined on the assumption that everyone knows what the shahāda is. The basic argument is that there was more than one version of the shahāda circulating in the Islamic world at the beginning of the eighth decade A.H./690s C.E. and that scholars need to define which version they mean when using the term “shahāda” for this early (...) period. Evidence for the argument includes data from stelae from Aswan to the Fatimid era, the Dome of the Rock and early Muslim coinage. (shrink)
