The ruling on a woman exposing her upper arm and leg before her mahram (relatives one may not marry) and women

The questioner:
May Allah reward you. The sister asking says: Is it permissible for me to expose my upper arm in the summer due to the intense heat in front of my mahram (relatives one may not marry) from whom I do not fear fitnah (trial, discord or temptation), and likewise in front of women? And is it permissible to expose a little of the leg in front of women?

The Shaykh:
It is not permissible to expose anything except the extremities: her head, her face, her palms, and her feet; there is no harm in that. As for exposing the upper arm or the leg, this is haram (forbidden) and not permissible, neither in front of women nor in front of her mahram (relatives one may not marry) men. Yes.

The questioner:
Honorable Shaykh Salih, meaning some of the sisters and some women in this present time have become lax in this matter, especially in occasions and celebrations.

The Shaykh:
Yes, this is a great munkar (what is wrong), and I seek refuge in Allah that, as they say, she dances and goes to the party. She exposes her back and her chest, and exposes her legs with her upper arms. This is among the munkar (what is wrong) that is not permissible to approve of, and it is not permissible for a Muslim woman to do it. It is obligatory for these women to repent to Allah, and to be modest and reserved. And if she goes out of her house, she should cover herself and be modest. Allah the Exalted said: Tabarruj (a woman's display of her adornment) is exposing the adornment when going out or in front of men. So she should not do this while she is a Muslim woman who fears Allah Mighty and Majestic. And if this has become widespread in parties, in rest houses, and in weddings, this does not make this action permissible; rather, it is haram (forbidden). And the more widespread it becomes, the stronger the prohibition is, and the more this munkar (what is wrong) appears, the greater its sin and the more its wrongness increases. Yes.
