What is the ruling on visiting non-mahram relatives who are not observing proper hijab, given the internal discomfort and inability to forbid them from this, as well as the act of greeting them?

It is not permissible for a man to enter upon his non-mahram female relatives, and they are obligated to veil themselves from him and cover their entire bodies. It is not permissible for them to display their adornments except to their mahram relatives. If the visit necessitates entering upon non-mahram women, then they must cover themselves and wear the legal hijab. It is not permissible to shake their hands or to be alone with them. Maintaining kinship ties is possible while avoiding religiously forbidden acts.
