الأَكِلُ وَالْمَأْكُولُ
The eater and the eaten.
Suppose some bodily matter belonging to one person is consumed by another human being and becomes incorporated into the second person's body. If both bodies must reclaim precisely that matter at resurrection, must one component simultaneously belong to two different bodies?
The objection particularly depends on the premise that all material constituents ever present in each body—including temporary nutritional additions—must return to each person. The distinction between original identity-bearing parts and later accretions tests that premise.
