Does sin befall one who severed ties with her cousin due to extreme harm, after she prayed against her and her prayer was answered?

Some scholars are of the opinion that a paternal aunt’s daughter (bint al-khalah) is considered kin (rahem) whose ties must be maintained. However, the more correct view is that maintaining ties with her is not obligatory, but rather highly recommended (mustahabb), based on the general evidence that commands maintaining ties of kinship and forbids severing them. Her wrongdoing and injustice do not negate the recommendation of maintaining ties with her, as long as it is possible to do so through greetings, prayers for her, and gifts. One will be rewarded for enduring her harm.

Boycotting (hajr) a paternal aunt’s daughter is permissible if it is to avoid her evil and harm. However, it is not permissible for a Muslim woman to boycott another Muslim woman without a legitimate شرعي (shar’i) reason for more than three days. If one is safe from her harm, then boycotting her becomes forbidden, and she is entitled to the rights of a Muslim woman over her sister.

Forgiving a paternal aunt’s daughter is better than supplicating against her. However, the supplication of one who has been wronged against their oppressor is permissible to the extent of the injustice, no more. Supplicating beyond the extent of the injustice is an act of oppression that incurs sin. One must repent and seek her forgiveness if the supplication was unjust. If seeking her forgiveness would harm her, then one should frequently supplicate for her and be kind to her without informing her.
