If a person prays in a mosque that contains a grave and does not know about it until after finishing the prayer, does he have to repeat the prayer?
Machine translationRead the Arabic original
The questioner : May Allah reward you with good. If a person prays in a mosque that contains a grave and does not know about it until after the prayer is finished, does he have to repeat the prayer?
The Shaykh : He does not have to repeat the prayer. But is the prayer valid in this mosque or not? In other words, is praying in this mosque forbidden or not?
Answer: If the mosque was built on top of the grave, it is obligatory to demolish the mosque, and praying in it is not permissible, because demolishing it takes precedence over demolishing the Mosque of Harm.
As for if the mosque existed before the grave, meaning the mosque was already standing and then a man was buried in it, the prayer in this mosque is valid, unless the grave is in the direction of the qiblah. The grave must be exhumed in any case and the person buried with the people, because burying him in the mosque is burial without right, and mosques were only built for the remembrance of Allah and prayer, not for burying the dead in them. So it is like someone buried in usurped land; he must be exhumed and placed or buried with the people.
