A:
One of the conditions of the validity of Salah is covering the `Awrah (parts of the body that must be covered in public). All of the woman's body is `Awrah during Salah, except her face if there are no non-Mahrams (not a spouse or permanently unmarriageable relatives) present. If a woman offers Salah while part of her hair or her foot is revealed, her Salah is not valid, because its conditions are not met.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
