idol worshipping. I think the person’s intention for swiping the tombstone is either to keep a memo or he/she want to prevent from idol worshipping which is of course haram in the Islamic context. There must be a reason why Nabi Muhammad (saw) did not choose a leader after his death; neither his closed friends or his family members, as he knew it will divide his followers and corrupt ppl will claim ownership either by blood or relation.
