The ruling on the dome over the Prophet’s grave and burial in buildings

Question:
The Shaykh said: It is reported that there is a dome over the grave of the Prophet (peace and blessings be upon him). Is this considered evidence for the reward of placing a vessel near these graves? And what is your guidance regarding this?

Answer:
It is not permissible. Regarding the dome, it is said that a dome exists, but they say this is not permissible. Maintaining the grave is not permissible. This is specific to the grave of the Messenger (peace and blessings be upon him), meaning he was buried in his house to preserve it, may Allah’s peace and blessings be upon him. As for anyone else, it is not permissible to be buried in a building or to have a building constructed over them. Rather, they are buried with the people in the desert in the graveyards.
The Companions, who are the most noble of the Ummah after the Prophet (peace and blessings be upon him), were buried in al-Baqi‘ and in the graveyards in the lands they went to. I do not build structures over them, nor do I erect falsehoods over them, and this is not permissible.
