The ruling on a woman’s prayer if her calves are exposed during prostration

Question:
May Allah reward you with good. The questioner says: If a woman prays in a garment that covers her entire body, but when she bows the garment rises and her two calves are exposed, is the prayer valid?

Answer:
If she was not aware of it, her prayer is valid. However, if she was aware and left part of her body exposed, her prayer is invalid, if that was a significant amount and she left it exposed while knowing about it. This is because covering the awrah (the part of the body that must be covered) is a condition of the prayer, and the entire body of a woman is awrah in prayer, except her face, if there are no non-mahram (a relative one may not marry) men present with her. Yes.
