Some philosophers denied bodily resurrection on the premise that iʿādat al-maʿdūm bi-ʿaynih—the numerically identical return of what has ceased to exist—is impossible. Their objection was that, if a person's body had been completely annihilated, producing a body later would produce another entity rather than restore precisely the first one.
The argument depends on its premises. It must establish that the identity-bearing constituents have necessarily been utterly annihilated, and then that numerical restoration is impossible. The decay or dispersal of a body does not itself demonstrate its complete annihilation.
