My friends and associates came and threw dust."
No matter how intimate the relationship, at the time of funeral, one's acquaintances will try to throw at least three handful of soil in the grave...as if this is the final haqq(right) of a friend. By action, the living imply, 'henceforth, it is you and your deeds.' One should visit the graveyard to reflect upon these realities and the life to come in the Akhirah.
