And the opposite of that is exaggeration regarding graves. For this reason: the Prophet (peace and blessings be upon him) forbade plastering graves, building on them, or writing on them.

The Shaykh : And the opposite of that is exaggeration regarding graves. For this reason: Mishkat al-Masabih 1697, because plastering it means glorifying and magnifying it, and this leads to associating partners with Allah with it. Likewise, building on it is so. Therefore, plastering is forbidden, and building is more severely forbidden. As for writing on it, there is a distinction:
As for writing that is intended only to establish the name to indicate the grave, there is nothing wrong with that.
As for writing that resembles what they used to do in the pre-Islamic age of ignorance: writing the person's name and praising him, stating that he did such and such, and other forms of praise, or writing verses of poetry, this is forbidden.
Also included in this is what some ignorant people do in lands other than ours—praise be to Allah, our land is pure from this. They write on the stone placed on the grave, for example, Surat al-Fatihah or other verses. All of this is forbidden. And whoever sees this in the cemetery must remove this stone, because this is from what is wrong that must be changed. And success is from Allah.
God’s messenger forbade that graves should be plastered with gypsum, that any erection should be built over them
