Benefits and Issues:
To place a plaque on the grave with the name and lineage of the deceased, or to inscribe his praise and commendation, or to write the name of Allah, His Messenger, or the Qur’an, all of these are impermissible.
However, it is permissible to place an appropriate marker for identification.
