The Sanaa Palimpsest: Physical Evidence of a Different Text

The Critique

In 1972, restoration work in the Great Mosque of Sanaa uncovered a cache of early manuscripts, among them a palimpsest (Sanaa 1 / DAM 01-27.1) whose erased lower text is the only surviving witness to a non-Uthmanic textual tradition, radiocarbon-dated with high probability to the mid-seventh century. The lower text differs from the standard Quran in word order, wording, omissions, and additions — far beyond spelling (Behnam Sadeghi and Mohsen Goudarzi, “Ṣan‘ā’ 1 and the Origins of the Qur’ān,” Der Islam, 2012; see also the Wikipedia and WikiIslam treatments). It corroborates the literary reports of companion codices: in the first decades, the Quranic text was fluid, and the uniformity that exists today is the product of Uthman’s standardization and later refinements — not unbroken letter-perfect transmission.

Common Muslim Responseshow Muslim scholarship answers

Muslim scholars respond that the lower text may be a student’s exercise, a private copy with errors, or one of the readings later abandoned under the ahruf concession; its erasure and correction to the standard text shows the community’s quality control working. Academic scholars (including Sadeghi) affirm the Uthmanic text itself is an early, well-preserved tradition going back to the Prophet’s recitations.

Counter-Rebuttalwhy critics find the responses insufficient

The critic accepts the academic consensus — and points out that it is fatal to the theological claim, not supportive of it. “The Uthmanic recension is old and stable” is a statement about one textual tradition that a caliph imposed while burning others; Sanaa 1 is direct physical proof that at least one different tradition circulated as Quran among believers. Perfect preservation of everything revealed is the doctrine; preservation of one edited recension is the evidence. Those are different claims, and Muslim apologetics routinely equivocates between them — a point made even by the Muslim-run Quran Variants project, which catalogues “bad apologetic arguments on Quran preservation.”
