The ruling on a menstruating woman entering the women’s prayer area attached to the mosque and following the imam

Question:
He says: Honorable Shaykh, may Allah grant you success. This is a group of women who say: We are a group of women who attend a lesson for one of the students of knowledge, and it is held in a place attached to the mosque, a prayer area that is always opened for the women’s prayer. However, there is an open space between it and the men’s mosque, and they share the same wall. The door of the prayer area opens onto the street, not onto the mosque. The question is: Is it permissible for a menstruating woman to enter it? And is it valid to follow the imam there?

Answer:
As long as it is within the mosque’s enclosure, it has the ruling of the mosque. As long as it is within the mosque’s enclosure, it has the ruling of the mosque, so it is not permissible for a menstruating woman to enter it. As for following the imam, there is no harm, because it is in the ruling of the mosque, being inside the mosque.
