Is it permissible to eat from a banquet prepared with mixed funds, some of which are unlawful, coming from the host's sale of alcohol, knowing that the host himself is retired and upright? And what is the ruling on sitting on furniture bought with unlawful money?

It has been previously established that the most sound opinion among scholars is that whoever purchases something with ill-gotten money, there is no harm in benefiting from that thing, because the unlawfulness is attached to the person's responsibility, not to the specific ill-gotten money itself. Therefore, it is permissible to accept this man's invitation, sit on these furnishings, or eat from this food, even if the source of all of this is the ill-gotten earnings of his children.
