Air condition has been installed in our masjid due to which we keep the inner door of the masjid and the middle door to the courtyard of the masjid closed. Some people are saying that because the door to the courtyard is closed, the Salah of those standing in the courtyard is invalid. But the voice of the Imam reaches them clearly. Is there any difference in the Salah of those standing outside in the courtyard due to the door being closed? The lines of those inside and outside of the masjid are connected. There is only a door between them.
As long as the lines are connected, there is no difference in the Salah of those standing in the courtyard of the masjid due to the door being closed.
