The ruling on a woman exposing her legs and upper arms before women

Question:
May Allah reward you. He asks: Does a woman sin if she wears clothing before women that exposes her legs and upper arms?

Answer:
Yes, she sins by doing so. It is not permissible for her to expose herself before women except what is permissible for her to expose before her father, her brother, and her mahram (relatives one may not marry). This is because Allah mentioned women alongside the mahram, saying, "But let them show their adornment to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, or the slaves their right hands possess." What is permissible for her to expose to a male mahram is permissible for her to expose to a woman, and what is not permissible for a man is not permissible for a woman. Yes.
