How can I deal with my aunt and her husband, who cause problems and seek to spoil relationships and incite hatred between us and others?

One must maintain a good relationship with people, and it is not permissible for the aunt and her husband to ruin this relationship. The aunt is like a mother and has a right to kinship ties, so it is advisable to be patient with her and offer advice to her and her husband with wisdom. If interacting with them leads to corruption, then avoidance is necessary, without a complete severance or bad manners. It is sufficient to check on them by phone. One should deal with them courteously and gently avoid their harm. If abandonment affects them and prevents them from evil, then there is no harm in it. However, if the harm is specific to you, then bear the aunt's harm while dealing with her courteously and safeguarding your religion. Kinship ties should be maintained as much as possible, while guarding against their harm and not allowing them to interfere in your lives.
