"Based on archaeology, script geography and areal linguistics in the Late Antique Roman-Byzantine Middle East (including Arabia), the Qur’an could not have originated in the Arabic script or language in the Mecca/Medina region. Current epigraphic and linguistic knowledge decisively contradicts the traditional narrative; one must instead look more closely at greater Syria, toward the Ghassanids and in particular the Lakhmids or the descendants of deported Arabs from in and around Merv. This is where the translation from Aramaic to Arabic script was completed. If these arguments for how and where the Qur’an was written down are examined, then much of its content will be easier to understand."
