Qurʾān · Uthmanic Text Type

Regional rasm variants

In the mid-7th century, tradition holds that ʿUthmān sent master copies to regional centers — traditionally Medina, Syria (likely Ḥimṣ, not Damascus), Basra, and Kufa. Early manuscripts overwhelmingly descend from one Uthmanic Text Type (UT) and are highly uniform. Medieval rasm literature and modern stemmatics record on the order of ~35–40 small consonantal or orthographic differences between those regional exemplars — not ~40 alternate Qurans. See our Hijazi witness timeline for dated leaves; Coverage explains what we do and do not collate.

What the scholarship says

Michael Cook (2004) tallies 16 Syria-unique, 13 Syria+Medina vs Basra+Kufa, and 6 Kufa-unique variants (~35 total) in Graeco-Arabica 9–10. Marijn van Putten (*Quranic Arabic*) summarizes ~40 variants in the consonantal skeleton between regional codices. Hythem Sidky (JIQSA 5, 2020) confirms four ancestral nodes by manuscript phylogeny.

Radiocarbon and palaeography place many of our Hijazi witnesses in or near the mid-7th-century canonization window. “Stable from ~650” means an early Uthmanic Text Type archetype, not zero scribal variation thereafter.

Stemma (Cook / Sidky)

Curated examples (33 of ~35–40)

Small consonantal/orthographic differences between the four ʿUthmānic regional exemplars (Syria/Ḥimṣ, Medina, Basra, Kufa) as recorded in medieval rasm literature and tested against early manuscript stemmatics — not alternate Qurans or qirāʾāt.
