The ruling on praying in a mosque that has a grave in its center and graves in its outer perimeter

Question:
May Allah reward you and do you good. The listener, Hamud al-Nazili from Yemen, sent a message containing a number of questions. In the first one, he says: There is a mosque with a grave in its center and a group of graves on its outer sides. The grave inside the mosque is at the back, and the worshipper cannot enter this mosque without walking over these graves on the outside. What is the ruling on praying in this mosque? Is it valid or invalid? Knowing that there is another mosque on his way that is being expanded and is free of graves.

Answer:
It is not permissible to pray in a mosque built over graves, because that is one of the means to shirk (associating partners with Allah). The Prophet (peace and blessings be upon him) forbade taking graves as mosques, and he informed that that is the practice of the Jews. He (peace and blessings be upon him) cursed the one who does that, and all of this indicates the severity of the prohibition and the invalidity of the prayer.
The obligatory thing regarding this mosque, if the graves are recent and the mosque is old, is to dig them up, move them away from the mosque, and bury them with the public cemeteries. And if the opposite is the case, that the graves are the old ones and the mosque was built over them recently, then it is obligatory to demolish the mosque and remove it from the graves. Yes.
