Repeating the prayer for one who prayed in a mosque and then learned that it contains a grave
Machine translationRead the Arabic original
Question:
Honorable Shaykh, may Allah grant you success, if I prayed in a mosque and then learned that it contains a grave, is it obligatory to repeat the prayer? Or is it analogous to the case of one who prayed while in a state of ritual impurity that he did not know about until after the prayer, in which case he does not repeat it?
Answer:
He must repeat the prayer if he prayed in a mosque that contains a grave. If the mosque was built over a grave and he prayed in it, he must repeat the prayer. This is because the Messenger (peace and blessings be upon him) forbade praying at graves and making them into mosques. The prohibition implies invalidity, so his prayer is defective; it is a defective prayer that is forbidden. Therefore, he repeats the prayer. Yes.
