We have an old cemetery whose traces were removed and it was renovated with tiles, and it became a mosque with a courtyard, so what is the ruling on praying

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: We have a mosque built on an old cemetery, such that they removed its traces by plastering and renovating its courtyard with modern tiles, so the graves no longer have any visible trace, and it became a mosque with a courtyard. The question is: What is the ruling on praying in this mosque?

Answer:
As long as the graves have not been removed, if the graves were dug up and relocated, and the need calls for this, then there is no harm. However, if the graves remain in the ground, then it is not permissible to pray in this mosque because it is built on graves, so it is not permissible to pray in it.
