Is it forbidden to pray in a mosque that has a grave next to it, but not inside it?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is it required that the grave be within the boundaries of the mosque, or does the prohibition of praying in it extend to what is around it, even if it is not within its boundaries?

Answer:
Anything connected to the mosque is not permissible. However, if it is separated from the mosque by a street, a passageway, or an open space, there is no harm in that. But if it is connected to the mosque, with its wall being the wall of the mosque, that is not permissible. Yes.
