Is it permissible for a woman to expose her hands or feet when she prays?

Question:
Honorable Shaykh, may Allah grant you success, if a woman’s hands or her hands and feet are exposed during prayer, is her prayer invalid?

Answer:
Yes, what is permissible for her to expose is only the face. If there are no non-mahram men present, she exposes her face, and she covers everything else; because the woman’s entire body is 'awrah (the part of the body that must be covered) in prayer except for her face.
