The ruling on a woman wearing thin, non-covering fabrics and the ruling on trading in them

Question:
May Allah reward you with good. Is it permissible to trade in women's thin fabrics, given that it is known that some people allow their female relatives to go out wearing them?

Answer:
It is not permissible to use thin fabrics that do not cover a woman, if it is known that they go out in them to the markets, for this is forbidden because they do not provide coverage. They fall into the category about which the Prophet (peace and blessings be upon him) said: "Clothed yet naked, swaying and causing others to sway; they will not enter Paradise nor smell its scent." This is because they wear clothing that does not cover, either due to its transparency and failure to conceal what is beneath it, or due to its tightness, or because it slips off the limbs, such that a woman's limbs are exposed, slipping off her legs, or her hands, forearms, and upper arms. This is forbidden clothing because it does not cover the woman, and it is not permissible to assist in sin. Allah the Exalted said: . If it is known from their custom that they use this for going out to the markets, then it is not permissible to promote it or assist them in it. Yes.
