Medieval Christian polemicists could read Muhammad’s revelations as akin to pagan oracles

Evidence

Legend also tells of how, when the young Muhammad accompanied a caravan, a pious Christian monk named Bahira recognized in him his future glory as a prophet. The Koran contains none of this; it makes only vague reference to the spiritual turmoil that preceded Muhammad’s call. On the contrary, the Koran emphasizes the simplicity and humanity of Muhammad; that is what makes the message all the more miraculous. The Hadîth dramatize this by having Muhammad fall on the ground and contort as he receives revelations via Gabriel, overpowered by the awesome presence of the Divine Word. — John V. Tolan, Saracens, 180

Categorization

• XREF: Bahira the monk — a Christian source legend — becomes a key node later European polemicists (from the Toledan Collection onward) use to claim Muhammad learned religion from a heretical Christian; genealogically roots tropes discussed in Anidjar/Aziz vault claims.
• QUESTION: How does the Bahira legend migrate from Muslim-approved (legitimating) use to Christian polemical (delegitimating) use in the Latin West? Worth tracing.
