What is the ruling on praying inside the mosque's sacred precinct if there is a grave on the mosque's wall outside the precinct?

Question:
A man built a mosque with his own money, and when this man passed away, he had bequeathed that he be buried inside the mosque, so he was buried inside the mosque's wall, but outside the sacred precinct. What is the ruling on praying inside the prayer area? And is it permissible to pray in this mosque in case of dire necessity?

Answer:
If the grave is inside the mosque's wall, inside the mosque's wall, then one does not pray in this mosque, because it is built over a grave. But you mentioned that the mosque is old and did not have a grave, and then the deceased was buried in it. This requires digging it up, exhuming it, and moving it to the cemetery, and clearing the mosque of it. As long as it remains in the mosque, it is not permissible to pray in it. Do you go to the other mosques that do not have graves? Yes.
