The ruling on building a small cement slab on top of a grave, on which the name of the deceased, the date of death, and some supplications are written?

Question:
He says: Honorable Shaykh, may Allah grant you success. I am from outside this country, and I have noticed that in our area, some graves have a cement slab made, measuring one meter in length by half a meter in width, with the name of the deceased, the date of his death, and some phrases written on it, such as “O Allah, have mercy on so-and-so.” What is the ruling on such an action?

Answer:
This action is forbidden. Yes. The Messenger (peace and blessings be upon him) prohibited writing on graves, prohibited lighting them, and prohibited building on them, because this is one of the means of shirk (associating partners with Allah) and exalting the deceased. When ignorant people come later, they say, “This is a wali (close friend of Allah) among the awliya (close friends of Allah),” and then they seek blessing from it and call for aid from it. Islam came to block the means that lead to the forbidden and to shirk, so it is not permissible to write on graves. Yes.
