Is money earned from working in a company that manages and maintains towers containing a gambling hall and cabarets, with the work restricted to monitoring general facilities without any direct interaction with these places, considered unlawful money?

Establishing gambling halls and cabarets is forbidden, and everyone who assists in them commits a sin, based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." If the work involves monitoring the facilities of a gambling hall and repairing any malfunctions in them, then it is a forbidden assistance in evil. However, if the work is limited to permissible areas and has no relation to the hall, its maintenance, or connecting utilities to it, then there is no harm in it.
