Ruling on praying in a mosque that has a grave in its center or in its qiblah

Question:
What is the ruling on praying in a mosque that contains a grave, and likewise the ruling on praying in a mosque that has a grave in its qiblah, but there is a barrier and a wall between them?

Answer:
The prayer is valid if the grave is outside the mosque. However, if the mosque contains graves, the prayer is not valid, even if there is only one grave.
Q: What if it is in the courtyard of the mosque?
A: If it is part of the mosque, one does not pray in it. If it is attached to the mosque, that is the case. But if it is outside the mosque and not considered part of the mosque, it does not harm.
Q: Meaning, if the barrier is present, whether it is in the qiblah or...?
A: On the right, left, front, or back, if it is outside the mosque, it becomes valid.
Q: What if it is in the direction of the qiblah of the mosque, and the grave is to the east of the mosque, near the restroom?
A: Outside the mosque, you mean?
The student: Yes, outside the mosque.
The Shaykh: It does not harm.
Q: What if the mosque was built on the grave, with separation, meaning it is isolated, but the mosque was built on the grave?
A: If it is outside the mosque, there are no graves in the mosque.
Q: But the mosque is built on it?
A: ...building mosques on graves... and it is not done unless it is inside.
Q: But it was not built except for it, meaning: the grave was placed and then the mosque was prepared afterwards?
A: As long as it is outside, what appears to me is that... its ruling is... removing the grave if it is feasible and transferring its remains to the cemetery would be further from doubt. The grave is transferred and removed.
Q: But it is the original one, even if we remove it, it is the original one?
A: It should be removed, even if it is the original one. It should be removed.
Q: What if it is the one that appeared...?
A: It should be removed... to keep it at a distance.
