The Conditions of a Woman's Hijab and the Ruling on Her Work

Question:
May Allah reward you and grant you good. The brother Ahmad says in his last question: We ask you, Honorable Shaykh, to explain to us the manner of a woman's hijab, and whether it is permissible for her to work alongside men or not?

Answer:
A woman's hijab is the loose clothing that covers her entire body from men, including her face and hands. It must be loose and roomy, not tight or soft enough to cling to her body, but rather spacious so that it does not reveal the shape of her body. It must be free of adornment that draws attention, free of imitating men's clothing, and free of imitating the clothing of disbelieving women. As the Messenger (peace and blessings be upon him) said, "Whoever imitates a people is one of them." This is the hijab of the woman that Allah the Exalted commanded in His saying, "And say to the believing women," and in His saying , as indicated by His saying, "And when you ask them for something, do so from behind a screen" .
And in His saying, "And when you ask the believing women for something, do so from behind a screen" . And in the hadith , among other evidence indicating that the hijab is for the woman to cover her entire body from non-mahram men. Yes.
As for a woman's work, it is permissible for a woman to do work that is befitting her, which does not take her out of the state of her femininity, and which does not involve mixing with men or seclusion with a man who is not one of her mahrams. So she does work that preserves her dignity and modesty and protects her from falling into what has no good outcome.
As for mixed work between men and women, or work that requires a woman to travel alone without a mahram, or work that requires a woman to be alone with a man who is not one of her mahrams, all of these are forbidden works for the woman, because of the great harms in them and the loss of sanctities.
