Evidence

In some cases of writers who knew little about bodies in hot climates, or did not think about what they knew, this happened after twelve or even fifteen days. The story seemed valuable to those who told it for its disproof of a hoped for miracle, but still more for the contrasts, sometimes explicit, sometimes implicit, between Muhammad and Christ. — Norman Daniel, Islam and the West, 609

• XREF: Directly supports the vault thesis of Islam as the West’s constitutive outside: the Prophet is defined entirely by negation of Christ’s ascension and incorruptibility.
