The ruling on hanging condolence papers on the doors of relatives

Question : Is there any permissible form of announcing a death that is widespread in some countries, where papers are printed and hung on the doors of the deceased's relatives or friends, stating the time and place where the condolence is accepted? Is this expansion also permissible, or is it not permissible?

Answer : It is called permissible. I see that this is an innovation (bid'ah) in one respect, and it may also be a cause for people to gather, which is a type of wailing.
