The ruling on a woman attending wedding parties where the parts of the body that must be covered are exposed

Question:
Sa'id asks: What is the ruling on a woman attending wedding parties where the 'awrah of the women is exposed?

Answer:
This is wrong, and may Allah protect us from it. This is a phenomenon that has become widespread now in women’s gatherings at rest houses or at wedding occasions, especially the young women who appear in a state of immodesty. They appear in a state of nakedness, and may Allah protect us from it. No one denies it, neither her guardian nor her mother nor anyone else, nor any of those present; rather, they boast about it. This is a great wrong and a serious danger to the Muslim community, and this happens in the meetings between women.
The one who is able to change this and able to prevent the women from it must attend in order to forbid what is wrong. As for the one who is not able to do that, it is not permissible for her to attend so that she does not incur sin, for she would be a participant. For the one who leaves off forbidding what is wrong while he is able to do so becomes a partner to its doer, because he has approved of it. So she should not attend.
