What is the ruling on a woman’s prayer if she exposes her feet during the prayer?

Question:
Honorable Shaykh, may Allah grant you success, if a woman exposes her feet during the prayer, does that invalidate her prayer?

Answer:
Yes, if any part of her body other than her face is exposed, and there are no non-mahram men present, her prayer is not valid unless she did not know or was unaware of it; in that case, the prayer is valid. But if she knew and left it exposed, she has prayed while exposing her 'awrah, because a woman’s entire body is 'awrah in prayer except her face, provided no non-mahram men are present. There is scholarly disagreement regarding the hands, and the correct view and the school’s position is that they are also 'awrah and must be covered. Yes.
