Is it permissible to visit or host a person who has bought something, like a table or a chair, with usury?

If a person takes out a usurious loan to purchase tools, it is not forbidden to deal with him, accept his invitation, or use his tools, while affirming the prohibition of usury and clarifying that it is one of the gravest sins. It is obligatory to advise him to repent. If he does not repent, then one should consider what is most beneficial: if shunning him would be effective in deterring him, then he should be shunned, while informing him of the reason. If maintaining connection while consistently advising him is more appropriate, then that should be done.
