Is the prayer valid with the congregation of the Haram from a room or apartment?

Question:
He says, may Allah reward you. It is clear. He asks: Is it permissible to sit in a room or apartment and pray with the Haram, whether one sees the mosque or not, while hearing the imam's voice?

Answer:
If the apartment is behind the imam in the mosque, and there is no open space between you and the worshippers, and the rows are connected to the apartment or room, then there is no harm, provided you can see the imam or those behind him.
