Epigraphic and Linguistic Forensics: Revalidating the Hijaz as the Original Locus of Early Islam

Over the past few decades, the traditional narrative regarding the origins of Islam in the Hijaz (Mecca-Medina) has been challenged by revisionist theories proposing Petra (Jordan) as the original birthplace of Islam. This theory argues based on the absence of archaeological evidence in Mecca and the advanced civilization of Petra. This paper refutes the Petra hypothesis by presenting a synthesis of the latest empirical evidence from four disciplines: Paleography (analysis of the Birmingham Manuscript and other early manuscripts), Epigraphy (rock inscriptions in the Saudi desert), Historical Linguistics (dialect and morphological analysis), and Comparative Archaeology. Findings indicate that the Birmingham Manuscript (ca. 568–645 CE) was writ- ten in the Hijazi script, which is a local evolution with characteristics distinct from the Nabataean tradition of Petra. Forensic linguistic analysis shows that the mor- phology, phonology, and orthography of the Quran reflect a pure Western Ara- bian (Hijazi) dialect, free from the Aramaic-Nabataean substrate dominant in Pe- tra. Furthermore, comparative analysis of toponyms, qibla direction, and the socio- economic context of the text reinforces the conclusion that the Hijaz was a zone of transit literacy that evolved independently, rendering the Petra theory invalid linguistically, chronologically, and geographically.
