Is it permissible to host someone who consumes ill-gotten gains, such as a neighbor who works for a tobacco company and partakes of its food?

Smoking, trading in it, manufacturing it, and working in its factories are all forbidden, based on the hadith: "Indeed, when Allah forbids the eating of a thing, He also forbids its price." Therefore, if the neighbor's entire income is from working in a tobacco factory, it is not permissible to eat or drink from what he bought with his unlawfully acquired money.
