Is working in the sale of clothes and shoes displayed on foreign models via Facebook, and answering customer inquiries and reserving orders—knowing that the customers are mostly non-Muslim women and their use of the clothes is unknown—permissible, and what is the ruling on the money earned from it?

Selling items that can be used for both lawful and unlawful purposes falls into three categories: It is impermissible to sell them to someone who is most likely to use them for unlawful purposes. It is permissible to sell them to someone who is most likely to use them for permissible purposes. If neither of these is known (as in online sales), the default ruling is permissibility. If the company displays its products with images of unveiled women, this is impermissible due to the display of unveiled women. However, this does not affect the lawfulness of the work as long as the seller does not directly engage in this display. It is recommended to advise those in charge of the website to avoid this.
