This is a study of the Quranic manuscript Arabe 334a held at the Bibliothèque nationale de France. It is a vocalized manuscript representing a Quranic reading tradition that falls outside the canonical ten reading traditions known to us today. It is shown that this manuscript, on the basis of verse division, is a Hijazi (probably Medinan) manuscript. The reading represented in the vocalization is likely also a non-canonical Hijazi reading. This article contains an edition of the folios of this manuscript and an in-depth study of the orthography, vocalization, verse division, and general principles and specific variants of the reading.
