Ruling on placing a marker on a grave or writing on it

Question:
The listener is Idris Muhammad, and his question is: Is it permissible to write on graves, or to place distinctive markers? May Allah reward you with good.

Answer:
As for writing on graves, it is not permissible; because the Messenger (peace and blessings be upon him) forbade it. Writing on them is not permissible, nor building on them, whether a mosque, a dome, or anything else. Rather, their earth should be restored, and the grave raised to the height of approximately one shibr, so that it is known to be a grave, and nothing should be added to it, nothing built on it, nothing written on it, and it should not be plastered. This is how the Messenger (peace and blessings be upon him) forbade it: he forbade plastering graves, sitting on them, building on them, writing on them, and adding to them anything other than their own earth; because this is among the causes of exaggeration.
So it is obligatory to leave that alone. As for marking the grave, there is no harm in it, whether by a specific stone, a piece of iron, a bone, or a board without any writing on it. There is no blame. The Prophet (peace and blessings be upon him) marked the grave of Uthman ibn Maz'un (may Allah be pleased with him) .
So the conclusion is that marking with a specific stone, a brick, a board, or something similar, is permissible. Yes.

The presenter: May Allah reward you with good, and may He do you good.
