Is a girl who vowed to fast three days of every month when she was thirteen years old—and had reached puberty at that time—considered bound by the vow despite the hardship she faces after her marriage and childbirth, and the impact of fasting on her health and her ability to care for her home, husband, and children?

Fulfilling a vow to fast three days each month after recovery is obligatory. If the inability to fast is temporary due to illness or household responsibilities, the missed days must be made up when able. However, if the inability is permanent, an expiation for breaking an oath (kaffarat yamin) is required, which entails feeding ten poor persons, clothing them, or freeing a slave. If one cannot do any of these, then fasting three days is required. It is not obligatory to feed one poor person for each day, contrary to some scholars who believe in the obligation of feeding in addition to the expiation for an oath in cases of permanent inability.
