The Latin canon of Islam was built from earlier Eastern Christian polemics.

Evidence

The ideas of Islam which Christians first formed under these conditions were absorbed and adapted by the Latin West; and it is the creation of a canon of what (according to the Latins) Muslims believe and do that is the subject of the present study. The integrated view thus created was purely European; but it had come to the Latins through their capacity to make the traditions of Greeks, of Arab Christians and, in Spain, of Mozarabs, their own. — Norman Daniel, Islam and the West, 46

• XREF: Complicates the vault’s West-versus-Islam binary: the ‘purely European’ view of Islam is itself mediated by Arab and Byzantine Christians — parallels Anidjar’s genealogical insistence that the Jew/Arab distinction is a Christian theological product.
• QUESTION: What specific Greek, Syriac and Mozarab texts carried these ideas into Latin — and when did the transfer happen?
