The Origins of Islam and the Limits of Revisionism: External Evidence, the Qurʾān, and Historical Method

Modern scholarship on the origins of Islam has frequently framed the problem as a tension between late Islamic historiography and earlier non-Muslim sources, often privileging the latter while subjecting the former to radical skepticism. This article reassesses that framework by evaluating Islamic historiography, external literary testimony, the Qurʾān, and first-century documentary and epigraphic evidence according to a single methodological criterion: explanatory adequacy. Rather than asking whether Islamic sources are immune to error, the study asks whether competing reconstructions of early Islam provide a more coherent explanation of the full evidentiary record. It argues that they do not. Early non-Muslim sources attest to the existence and authority of a prophet named Muḥammad within years of his death; the Qurʾān functions as contemporaneous internal evidence presupposing a living messenger, an organized community, and binding normativity; and material culture—coins, inscriptions, papyri, and monuments—publicly anchors Prophet Muḥammad’s prophetic identity within the first Islamic century. While legitimate uncertainty remains regarding fine-grained narrative detail, no alternative reconstruction accounts for this convergence without introducing greater explanatory strain. The article concludes that, when read critically and comparatively, the traditional Islamic narrative framework remains the most historically plausible account of Islam’s origins currently available.
