Ruling on building mosques over graves and the reverse

The question: In his second question, he asks: What is the ruling on building over a grave? He means building a mosque.

The answer: As for building over graves, it is forbidden, whether it is a mosque, a dome, or any other structure; that is not permissible. This is because the Messenger of Allah (peace and blessings be upon him) cursed the Jews, saying: The curse was due to their taking mosques over graves. This indicates the prohibition of building over graves and that it is not permissible. Taking them as mosques is one of the causes of fitnah (trial, discord or temptation) regarding them; because when mosques are placed over them, people are led astray by them, and they may call upon them instead of Allah and seek aid from their occupants, leading to shirk (associating partners with Allah). In the hadith of Jundub ibn 'Abd Allah al-Bajali in Muslim's Sahih, the Prophet (peace and blessings be upon him) said: Thus the Prophet (peace and blessings be upon him) warns us against taking mosques over graves.
Therefore, the people of Islam should beware of this; indeed, it is obligatory for them to beware of it. In the hadith of Jabir in Muslim, the Prophet (peace and blessings be upon him) said: If a mosque or dome or the like is built over a grave, people exalt it and are led astray by it, and it becomes one of the causes of shirk with it, and calling upon the occupants of the graves instead of Allah (Mighty and Majestic). This is the reality in many countries and lands, where graves are exalted and mosques are built over them, and the ignorant people circumambulate them, call upon them, seek aid from their occupants, make vows to them, seek blessing from their graves, and rub against them. All of this occurred due to the causes of building over graves and taking mosques over them. This is from the ghuluw (exaggeration) that Allah has forbidden. The Prophet (peace and blessings be upon him) said: And he said: meaning: the extremists who exaggerate.
In summary: It is not permissible to build over graves, whether a mosque or not, or a dome. This is from the great prohibitions and from the means of shirk, so it is not permissible to do it. If it occurs, it is obligatory for the rulers to remove it and demolish it, and that no mosques or domes remain over the graves. Rather, they should remain open and exposed, as was the case in the time of the Prophet (peace and blessings be upon him) and the time of his Companions (may Allah be pleased with them and grant them satisfaction) and the righteous Salaf. And because building them—building mosques over graves—is from the means of shirk. Likewise, domes and other structures are all from the means of shirk, so they are not permissible. Rather, it is obligatory to remove and demolish them; because that is the requirement of the command of the Prophet (peace and blessings be upon him). It is a command of the one upon whom be peace and blessings that graves be visited for remembrance and admonition, and he prohibited building over them and taking mosques over them; because this makes them places of worship for those other than Allah, makes them gods, makes them idols worshipped other than Allah. So it is obligatory to obey his command regarding visiting, meaning it is prescribed for us to obey his command regarding visiting. Visiting graves is recommended (mustahabb). It is prescribed for us to visit them for remembrance and to supplicate for their occupants with forgiveness and mercy. But we do not build over them, neither mosques nor domes, nor other structures; because building over them is from the means of shirk and fitnah (trial, discord or temptation) regarding them. Yes.
The presenter: He asked a third question, but the answer was interrupted, and he says: What is the ruling on placing a grave as the qiblah (direction of prayer) of the mosque inside it? And you have spoken about...
The Shaykh: This.
The presenter: Yes, yes. As for his fourth question, he says: We heard in your program...
The Shaykh: Here is another issue, which is: placing graves in mosques. Burying the dead in the mosque is also not permissible. Some people, when they die, say: Bury me in the mosque. This is not permissible; burying him in the mosque is not allowed. Rather, he must be exhumed and moved to the cemetery. If he is buried inside the mosque, he must be exhumed and moved to the cemetery, and it is not permissible for him to remain in the mosque at all. This is the obligation upon the people of Islam: not to bury in mosques. Meaning, no one has the right to be buried in a mosque. Rather, if someone is buried in a mosque, he must be exhumed and moved to the public cemetery. Yes.
