Details on the limits of a woman's 'awrah (part of the body that must be covered) in prayer

Question:
The caller, Misha'a Sa'd from al-Jubayl, asks: Is it permissible for a woman to pray in her house wearing short clothing that ends below the knee, whether she is with her husband or alone, or is she required to cover her entire body, even though there is no one in the house except her husband?

Answer:
A woman in prayer is entirely 'awrah (part of the body that must be covered) except for her face, provided there are no non-mahram (a relative one may not marry) men present. If there are non-mahram men present, she must cover her face and her entire body. The clothing required for prayer differs from the clothing worn outside of prayer. It is obligatory for the woman praying to cover her entire body, even if no one is present except her face; she may uncover her face if she is free of non-mahram men.
