Is it permissible to purchase furniture from a store, only to find out later that its owner had previously used money earned from selling alcoholic beverages to establish it?

It is forbidden for a Muslim to sell alcohol. If someone has done so and repented, we ask Allah to accept their repentance. As for the money earned from selling alcohol, it must be disposed of by spending it on charitable causes. However, whatever was sold alongside it, such as the furniture of the place and similar items, its sale is permissible because it can be used for purposes other than alcohol. Thus, the money obtained will be mixed with lawful and unlawful elements. Dealing with this person and buying furniture from them is permissible.
