Is a woman sinful if she does not respond to the request of her neighbor who adjures her by an oath to partake of food and drink and to stay, knowing that she cannot tolerate visiting her due to the frequency of her adjurations?

Fulfilling an oath is a right of a Muslim upon their Muslim sibling; it is commendable, not obligatory. It is desirable to fulfill an oath unless it leads to something forbidden or causes hardship. Therefore, the questioner is not sinful for not fulfilling her neighbor's oath concerning eating, drinking, or staying with her, especially if she feels embarrassed. She should not, however, cease her visits, for the rights of a neighbor are great.
