Can an elderly man, who is unable to fast and relies on charity, feed a single needy person after obtaining money to complete the expiation for breaking an oath? What is the amount of feeding for expiation of an oath and for the redemption of fasting? Is the expiation for swearing an oath given precedence over the redemption for Ramadan?

It is permissible for the one who breaks an oath to feed, as expiation, one or more poor persons each day, or to feed them separately. The obligation is to feed ten poor persons, and it is not valid to feed a single poor person, according to the majority of scholars. It is not necessary for them to be gathered together. The amount of food for each poor person is approximately 750 grams of rice. Scholars have differed regarding the obligation of feeding for those who are unable to fast due to old age or an incurable illness. The majority of scholars hold it to be obligatory for the one who is able, while the Malikis consider it recommended. Its amount is approximately 750 grams. It is waived for those who are unable to provide it, according to those who deem it obligatory. If the obligatory feeding for an oath conflicts with feeding for someone unable to fast, it appears that the expiation for the oath takes precedence.
