What is the ruling of Islamic law concerning a woman who swore an oath to her brother that he must take money for land she bought from him, but the brother refused, so a third party intervened and divided the amount equally between them, and the woman took her share and expiated her oath by fasting three non-consecutive days, then gave a sum of money in charity to two poor people? Has she expiated her oath, and is anything else required of her?

The sister mentioned has broken her oath, and expiation (kaffarah) is obligatory upon her because her brother did not accept the full amount. For this expiation, fasting is not sufficient except when one is unable to feed, clothe, or free a slave. Furthermore, according to the majority of scholars, it is only sufficient to give it to ten poor persons. The expiation remains her responsibility if she is capable of performing it in a way other than fasting. It is permissible to pay money for it if doing so results in a predominant benefit for the poor.
