Christians invented false miracles about Muhammad that Muslims never claimed.

Evidence

In quite a different category are those false miracles, which no Muslim ever claimed, but which entered early into Christian legend about Islam: the dove that whispered in the Prophet’s ear, the bull that bore the Law in its horns, and so on. To Vincent they suggested the ‘model of Moses’ but really they are pagan, non-Arabic and non-Islamic in origin; see Ziolecki. — Norman Daniel, Islam and the West, 2013

• SEED: An article angle: how religious polemics fabricate apocryphal ‘evidence’ against rivals that the target never claimed — a cross-cultural pattern from the dove-and-bull legends to modern smear campaigns.
• XREF: connects to: Aquinas denied Islam any authority because it lacked miracles and true documents
