Are there days when one should avoid fasting if the fast is an expiation for a false oath?

The days on which fasting is forbidden are: the day of Eid al-Fitr, the day of Eid al-Adha, and the three days of Tashreeq that follow Eid al-Adha. Fasting as expiation for an oath is only permissible when one is unable to feed ten poor people, clothe them, or free a slave, as stated in verse 89 of Surat Al-Ma'idah. As for the false oath (al-yamin al-ghamus), the majority of scholars hold that no expiation is required for it; rather, sincere repentance is obligatory.
