Is the woman who severs ties with her brother, who wronged her and seized her inheritance from their father, held accountable?

The injustice and abuse of a brother do not justify cutting ties with him, because maintaining kinship ties is obligatory, and severing them is a grave sin. It is permissible to take the matter to court to reclaim one's rights, and the supplication of the oppressed against the oppressor is permissible, though forgiveness is preferable. The supplication should not exceed the measure of the injustice. Therefore, it is advisable to refrain from supplicating against the brother and to reconnect with him.
