The ruling on praying in a mosque that contains graves

Question:
The questioner says: In some countries, there are graves inside their mosques. They do not contain wealth, but they are graves with shrines for seeking blessing. Is it permissible to pray in them?

Answer:
If there is no wealth in them, are they just stones? No, they are not considered shrines, but I do not think there is anything of this kind, nor is there any report about it. It is only said that the grave of al-Husayn is a fabrication, because al-Husayn did not go to Egypt, and the head of al-Husayn did not go to Egypt, and nothing of al-Husayn is in Egypt (may Allah be pleased with him). Rather, he was buried in Iraq in Karbala; he was buried in Karbala, yes, he was buried in Karbala. It is said that the place where he was buried, his head was carried to Sham, Allah knows best. The point is that the matter did not happen. Some say that what is in the grave is not al-Husayn, but rather one of the Fatimid Shi'ah is buried there. In any case, I do not know the truth of this matter. However, if it is established that this grave does not exist, or that this mosque does not contain a grave, then there is no barrier to praying in it. Yes, Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad.
