Is a person considered an accomplice to the forbidden if he works as an accountant for a hotel that serves alcohol, while trying to avoid dealing with alcohol accounts and donating a portion of his salary corresponding to the duration of his work at the hotel?

As long as you strive in your work to distance yourself from anything related to alcohol, we hope that you are not an assistant in that which is forbidden concerning it. It is permissible to engage in lawful dealings with someone whose lawful wealth is mixed with unlawful wealth. Scholars have used as evidence the fact that some Companions of the Prophet, peace and blessings be upon him, hired themselves out to Jews during his time.
