The ruling on a woman exposing the backs of her feet in prayer

Question:
May Allah reward you with good, and may He do you good. Tell us about a woman praying without covering her feet, with the evidence?

Answer:
It is permissible for a woman to pray with her feet uncovered, because her feet are part of the 'awrah (part of the body that must be covered) that she is required to cover in prayer. The evidence for this is that Asma' asked the Prophet (peace and blessings be upon him): "Does a woman pray in a thobe (a long, loose garment)?" She asked the Prophet (peace and blessings be upon him): "Does a woman pray in a thobe?" Meaning a long, loose garment. He said: "Yes, if it is long enough to cover the backs of her feet, to cover the backs of her feet." This indicates that the feet are part of the 'awrah and she is required to cover them. If she prays with her feet uncovered, her prayer is not valid because she did not cover her 'awrah. Yes.
