Jurisprudence by Imam Khamenei;
Q1082. Is it permissible to
work in nightclubs, food processing factories, where pork is usually
processed, or any other corrupt centers? What is the ruling on money
earned from such work?
A: It is not
permissible to be involved in any ḥarām act, such as selling
intoxicants, setting up and managing nightclubs and other places for
lewd behavior, gambling, and consumption of alcohol. Furthermore, any
income earned in such a way is ḥarām and one does not own the wages
taken for it. As to pork, it is caution to avoid earning money through
it.
