What is the ruling on working in women's salons where forbidden acts are committed, such as plucking eyebrows (al-nams), uncovering 'awrah (parts of the body that should be covered), and displaying channels and images of male and female singers?

The ruling on opening beauty salons and the ruling on a woman exposing her body in them have been previously explained. It is authentically reported that the Prophet, peace and blessings be upon him, "cursed women who perform tattoos and those who have them performed, women who pluck eyebrows and those who have them plucked, and women who separate their teeth for beauty, altering Allah's creation." A Muslim woman must avoid what Allah has forbidden, and it is not permissible for her to assist those who commit sins, thus sharing in their transgression. It is incumbent upon those in authority over Muslims to enjoin good and forbid evil, and to deter transgressors. "Indeed, Allah restrains with authority what He does not restrain with the Qur'an."
