Reassessing Dan Gibson's Demographic and Commercial Arguments for Petra: A Critical Study of Early Arabic Historical Sources

Abstract

This article critically examines one of the principal arguments advanced by Dan Gibson in support of his revisionist hypothesis that Petra, rather than Makkah, was the original sacred city of Islam. Gibson argues that the military and commercial activities attributed to the Quraysh in the early Islamic sources presuppose a large urban center with substantial demographic and economic capacity, a description which, in his view, cannot correspond to present-day Makkah. Employing a qualitative historical-analytical methodology, this study re-examines the primary Arabic historical sources upon which Gibson relies, particularly Tārīkh al-Ṭabarī, alongside classical sīrah literature and relevant geographical evidence. The analysis identifies a series of methodological shortcomings in Gibson's treatment of the evidence, including inaccurate citation of primary sources, reliance on selective quotations, misinterpretation of historical reports, and insufficient engagement with the original Arabic texts. Furthermore, the study demonstrates that several historical incidents cited by Gibson, when read in their full textual and geographical context, directly contradict his reconstruction by confirming the traditional trade routes between Makkah, Madinah, and Syria. It also shows that the numerical strength of the armies cited by Gibson largely reflects tribal coalitions rather than the population of Makkah itself, while the value of Quraysh commercial caravans cannot be used as a reliable indicator of urban population size. The article concludes that Gibson's demographic and commercial argument rests upon flawed historical interpretation and does not provide convincing evidence against the traditional identification of Makkah as the original sacred center of Islam. More broadly, the study highlights the necessity of contextual reading, accurate source criticism, and direct engagement with primary Arabic sources in reconstructing early Islamic history.
