LifeCycle Events: Death, Burial, and Bereavement: Burying things with a Body:
Is it permitted to bury things with a body?
If something were "offered" to the dead as a sacrifice
it would be forbidden; see Psalms 106:28. The things
"given to" the dead are being destroyed or buried with
them as an expression of grief; such things too become
forbidden like the body itself.
