Is there evidence for the prohibition of prayer in mosques that contain graves, or is it a matter of blocking the means to harm?

Question:
He says: Honorable Shaykh, may Allah grant you success. The prohibition of prayer in mosques that contain graves, is there evidence for it? He says: Is there evidence for the prohibition of prayer in mosques that contain graves, or is it merely a matter of blocking the means to harm?

Answer:
No, glory be to Allah, there is evidence for it. The Messenger (peace and blessings be upon him) said: Meaning, do not pray facing them. The mosque is not limited to a built structure; the prayer facing them is what makes it a mosque. Whoever prays in a place has made it a mosque. He (peace and blessings be upon him) said: Prayer at the graves is making them into mosques. Even if there are no built mosques there, it is not permissible. The Messenger prohibited it in many hadiths and informed us that it is the practice of the Jews and the Christians. Yes.
