Is an expiation for a broken oath (kaffarat al-yameen) sufficient for a person of means if the money he will pay is from his family's wealth, and is it valid to fast three days as expiation for a broken oath?

The expiation for an oath (kaffarat al-yamin) follows the order mentioned in Surat Al-Ma'idah, Ayah 89, which is: feeding ten poor persons with the average food you feed your own families, or clothing them, or freeing a slave. Whoever cannot find [the means], then he must fast for three days.

The required amount for feeding is half a Saa’ for each poor person (approximately 1.5 kg of rice or similar). It is permissible to feed them lunch or dinner. For clothing, a shirt for each poor person is sufficient.

It is not permissible to move to fasting if one is able to feed, clothe, or free a slave. Whoever fasts while being capable, his fast will be considered supererogatory, and he must still perform the obligatory expiation.

Moving to fasting is permissible for someone who does not find what to expiate with, in excess of his food for the day and night and his basic necessities.

If a person was capable of performing the expiation when he fasted, then his fast is not sufficient, and he must repeat it. However, if he was not capable, his fast is sufficient. In case of doubt, the expiation should be repeated. If it becomes clear that the first fast was insufficient and the person is now unable, then he should fast for three days.
