Some people leave their trusts and possessions by the graves of pious people, thinking that the dead will guard them and that they will not be stolen, rifled, or taken.
Believing that the dead can guard what is put (Part No. 3; Page No. 98) by their graves is open Kufr (disbelief) and also involves Shirk (associating others with Allah in His Divinity or worship) that merits, for those who die while still doing this, eternity in the Fire. It is, therefore, not permissible to leave trusts or other possessions by graves for them to be guarded or blessed.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
