Is it permissible to place a metal plague or a “sign” inscribed with some Ayahs (Qur’anic verses), the name of the deceased person, and the date of his death on the grave?
A: *It is not permissible to inscribe Qur’anic Ayahs or anything else on graves. Likewise, it is not permissible to use an iron plaque, board, or otherwise. It is authentically reported on the authority of Jabir (رضي الله عنه) that the Prophet (صلى الله عليه وسلم) forbade plastering of graves, sitting on them, and building on them. Related by Imam Muslim in his Sahih.* According to the narration reported by at-Tirmidhi and An-Nasa’i with (authentic) Sanad (chain of narrators), the following addition is found: and [forbade] inscribing on them.
