Is it permissible to cut ties with paternal aunts who cause familial problems, divorce, and discord, and what are the limits of kinship ties (silat al-rahim) as enjoined by Islamic law?

The kin whose ties must be maintained are blood relatives from both parents, and they are divided into mahram (those with whom marriage is forbidden) and non-mahram.

Maintaining kinship ties (silat al-rahim) is not abrogated by their ill-treatment. Rather, what is abrogated are the forms of connection that lead to their ill-treatment, such as visits and conversations, while other forms remain, such as supplication, offering assistance, and checking on their well-being.

As for shunning (boycotting), it is divided into permissible and forbidden. Shunning for self-preservation that exceeds three nights is forbidden. Shunning for a legitimate religious benefit, such as shunning innovators or disobedient individuals, is permissible. Permissible shunning does not negate the obligatory maintenance of ties, whereas forbidden shunning does.

What the aunts did by harming, severing ties, and backbiting is considered a major sin. However, this does not abrogate the obligation to maintain ties with them through means of connection that ensure safety from their harm.

Refraining from speaking to them is permissible if it falls under permissible shunning, or if it is to guard against their harm. Other forms of connection remain, such as greeting them and supplicating for them. This applies to the sisters' daughters, as the aunts are mahram relatives. As for the mother, the aforementioned rules of shunning apply to her if she is not related to them by blood.
