What is the ruling on buying inexpensive grains for the expiation of an oath if the price of rice is higher than that of wheat? And what is the difference between a needy person (miskin) and a poor person (faqir)? And is a family that owns a simple house but cannot find enough food for themselves considered a needy family or a poor family?

The obligatory expiation for an oath is to feed ten poor people, with each person receiving approximately 750 grams of the staple food of the land. It is permissible to give the expiation to a poor family that does not have enough to meet its needs, even if they own a simple house, provided that the family consists of ten or more members. The expiation should be paid for only ten of them if their number exceeds that. Those eligible for the expiation are the poor or the needy.
