Ruling on grave markers on which are written details of the deceased
Question

                Is it permissible to put a piece of metal or a marker on a grave on which is written verses of the Qur’aan in addition to the name of the deceased and the date of his death, etc.?
Praise be to Allah.It is not permissible to write anything on the grave, whether it be 
          verses of the Qur’aan or anything else, on iron, stone tablets or anything 
          else, because it was reported from Jaabir ibn ‘Abd-Allaah (may Allaah 
          be pleased with him) from the Prophet  
          (peace and blessings of Allaah be upon him) that it is forbidden to 
          plaster the walls of graves, to sit on them or to build over them. This 
          was narrated by Imaam Muslim in his Saheeh; al-Tirmidhi and al-Nasaa’i 
          added, with a saheeh isnaad, “or to write on them.”
