The Ruling on a Woman uncovering her Hands and Feet in Prayer
Question :
What is the ruling on showing the feet and hands for a woman in prayer, bearing in mind that she is not in front of men, but in her house?
Answer:
What is well known in the Mathhab of the Hanbalis - may Allah have mercy on them is that all of an adult, free woman is 'Awrah in prayer, except her face; and based upon this, it is not permissible for her to uncover her hands or her feet, though many scholars hold that it is permissible for a woman to uncover her hands and feet. But the safest thing for a woman is to beware of that, although, if it happened that a woman did so, then she sought a ruling on the matter, no person should venture to order her to repeat her prayers.
