What is the expiation for someone who swore on the Qur'an that she would not accept her suitor, and then did?

Swearing by the Mus'haf (the Holy Quran) constitutes a binding oath, for which expiation is due from the one who breaks it. This expiation involves feeding ten poor people, or clothing them, or freeing a slave. If one is unable to do so, then fasting for three days is required, based on the Almighty's saying: {Allah will not impose blame upon you for what is unintentional in your oaths, but He will impose blame upon you for what you intended in your oaths. So its expiation is the feeding of ten needy people from the average of that which you feed your [own] families or clothing them or the freeing of a slave. But whoever cannot find [or afford it] - then a fast of three days. That is the expiation for your oaths when you have sworn. And guard your oaths. Thus does Allah make clear to you His verses that you may be grateful} (Al-Ma'idah: 89). It is noteworthy to highlight the virtue of marriage and not to reject a suitor who possesses good character and religious commitment. It is also commendable to expiate an oath if one sees what is better than it.
