In some graveyards, they say: Raise the grave and we will build it up, even if it is more than a shibr, on the grounds that it will sink later.

Question:
He says: Honorable Shaykh, may Allah grant you success. When we go to bury one of the deceased, we hear from some people, and perhaps from those in charge of some of the washing places for the dead, that they say: Raise the grave and we will build it up, even if it is more than a shibr, on the grounds that it will sink later. What is the correct position regarding this?

Answer:
Whatever opens this door—raising it to the height of a shibr, built up as the grave of the Messenger (peace and blessings be upon him) and the graves of his Companions were—should not be done on the grounds that it might sink later. It is not our concern; the important thing is to apply the Sunnah. If it sinks later, there is no harm. If it sinks, bring more earth and put it on top; that does not contradict the ruling. If you fear that water will collect on it or that it will be trampled, that does not contradict the ruling. Bring earth and put it on top, or bring gravel and put it on top. Yes.
