Is importing and selling artificial eyelashes permissible (halal) or forbidden (haram), especially after learning of their prohibition except in cases of necessity (ʿudhr)? Is the money earned from them lawful (halal)? And what should be done with the current money and stock?

Artificial eyelashes are forbidden. That which is forbidden to use is also forbidden to sell and to profit from its sale. Therefore, it is not permissible to work in this field or to sell these products, except to someone known to use them for permissible purposes, such as to correct a disfigurement or for treatment. Whoever fears Allah, He will suffice him and replace it with something better. Money earned previously from selling these items, before knowing their prohibition, is not forbidden to benefit from.
