Should I leave the mosque during the Friday prayer after the imam has ascended the pulpit because I discovered that there is a grave in it?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I entered a mosque for the Friday prayer, and I found that the imam had ascended the pulpit, then I found a grave in the mosque. Should I pray in this mosque, or should I leave it and pray in another place?

Answer:
Leave it; do not pray in it. As long as you saw that the mosque is built over a grave, do not pray in it, because the Prophet (peace and blessings be upon him) forbade you from praying in a mosque that contains a grave. Go out and pray in another mosque that does not have a grave.
