What is the ruling on maintaining ties of kinship with relatives characterized by envy, the evil eye, backbiting, and ill-suspicion, knowing that they initiated these behaviors and that both parents have passed away?

Fear of envy does not nullify maintaining kinship ties. Therefore, it is permissible to visit relatives without disclosing detailed news, while enjoining them against backbiting and gossip, and avoiding their presence during such gatherings. Kinship ties must be maintained, even with the bare minimum required, and one must beware of severing ties with maternal uncles and aunts, even if they behave poorly.
