The land is earthen, so we dig it to level the grave, and we build it with fired brick; what is the ruling?

Question:
The questioner, your brother in Allah Abu Ali, has a set of questions. In this question he says: Our land is earthen, so we dig it to level the graves, and we build them with fired brick. What is your opinion, Your Eminence Shaykh Abdulaziz?

Answer:
It is obligatory for you to dig only; as for building, do not build anything; because the Messenger of Allah (peace and blessings be upon him) But you dig a hole to half a cubit, for example, then you place a niche in it, then the deceased is buried; he is placed in the niche, and bricks are set up over it, then earth is thrown over it, and it is raised above the ground by the width of a hand with clay so that it is known to be a grave, and markers are placed at its ends to preserve its earth.
As for building anything on it, nothing is to be built on it. Rather, the earth is placed over it when the bricks are set up. The bricks are set up, and the space between the bricks is filled with clay and the short ends of the bricks, then earth is thrown over it, and it is raised by the width of a hand. The earth—the earth of the grave—is raised so that it is known to be a grave.
As for building anything on it, from the inside or from the outside; it is not permissible. The Messenger prohibited plastering graves, prohibited sitting on them, and prohibited building on them—(peace and blessings be upon him). Yes.

The presenter: May Allah reward you with good, O Shaykh.
