Q: In taraweeh salaah can women follow the men in a separate room and can we read behind non-mahrams?
A: Women may not follow a jamaat that is in a separate room. For the jamaat to be valid a muqtadees must be in the same room. It not permissible to read behind non-mehrams. If the jamaat consists of mehram males then the females may follow provided a screen separates them. Also note that this applies to the Taraweeh congregation that takes place at home. It is not permissible for females to attend the musjid for taraweeh salaah.
