Is working at a men's massage center that offers a massage booking service with a female trainer considered unlawful (haram)?

It is impermissible for a woman to work as a masseuse for men, due to the forbidden looking and touching involved. Allah (the Exalted) says: "Tell the believing men to reduce [some] of their gaze and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do. And tell the believing women to reduce [some] of their gaze and guard their private parts." And the Prophet (peace and blessings be upon him) said: "For one of you to be stabbed in the head with an iron needle is better for him than that he should touch a woman whom it is not permissible for him to touch." It is also impermissible to book appointments for women's massages for men, as this constitutes aiding in sin. Allah (the Exalted) says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty."
