Is it permissible to work as an accountant for a company that provides hotels with bars for alcohol and dancing, and is the salary earned from this work unlawful?

It is not permissible for a company to lease workers to hotels that have bars and nightclubs if the work takes place in forbidden areas, or in them and other areas. If the company's work is entirely in the forbidden, then it is not permissible to work for it. However, if its work is originally permissible and it contracts for what is not lawful, then it appears permissible to work for it, provided that one does not undertake to conclude a forbidden deal.
