Is it permissible to pray in a mosque next to which there is a shrine?

Question:
The questioner asks: What is the ruling on praying in a mosque that has a shrine in front of it, with nothing separating the two except the door and the shrine building? And what is the ruling on praying in a mosque named after the person in this shrine?

Answer:
A mosque built over a shrine is not to be prayed in; the prayer in it is not valid. This is because the Prophet (peace and blessings be upon him) forbade praying at graves, and he said: . He cursed them while he was in his final moments before death, saying: “May Allah curse the Jews and the Christians who took the graves of their prophets and righteous people as mosques. They are warned of what they did.” So, do not pray in a mosque built over a shrine, and the prayer in it is not valid, because it is not a mosque; rather, it is a shrine, a shrine site where you do not pray. However, if the grave is far from the mosque and separate from it, with land or streets between them, there is no harm. But if the grave is inside the mosque or connected to the mosque, beware, beware that you are praying in it, for the Messenger warned you against this. He said: “Do not take graves as mosques.” This is a warning from the Messenger, not from us. The Messenger said: . He said this while in the context of death, (peace and blessings be upon him). So, stay away from mosques built over graves, and call people to Allah, making it clear that these are not valid mosques but rather places of idolatry. The Messenger warned against them and forbade the community from them. This is the obligatory duty. It is obligatory for Muslims to bury the dead in cemeteries, not in mosques. This is what the Messenger (peace and blessings be upon him) did; he buried his Companions in al-Baqi', not in mosques. They were the best of the community, yet he did not bury them in mosques; he buried them in al-Baqi', in the cemetery. This is the Sunnah of Islam, the Sunnah of the Messenger (peace and blessings be upon him). Yes. May Allah reward you.
