Is it permissible to work in the art of gypsum for hotels, usurious banks, and liquor stores?

Working with gypsum is permissible, but it becomes unlawful if it leads to or aids in something unlawful, such as applying gypsum for interest-based banks or alcohol shops. This is considered aiding in sin, which Allah Almighty has forbidden: "And do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty." As for applying gypsum for hotels, there is no objection to it, because hotel work is permissible in principle, even if it occasionally contains unlawful elements.
