Is her work valid and permissible since she does not work on eyebrows? Is there sin in the mixing of money and its division with her partner who practices eyebrow plucking (namṣ)? Is partnering with her a sin?

A woman's work in adorning other women is permissible if it involves what is lawful, but it becomes forbidden if she knows that the woman is adorning herself for prohibited display (tabarruj), due to Allah's saying: "And do not cooperate in sin and aggression." Likewise, it is not permissible to participate with someone who performs the forbidden plucking (namṣ), which is the removal of facial hair, unless a woman grows a beard or mustache. Accordingly, if unlawful money is earned from this work, she must desist from it.
