Is it permissible for the expiation of feeding sixty poor people to be uncooked (raw) rice? Is it permissible to distribute it all at once to one poor family? And what is the amount of food per person?

Feeding sixty destitute persons as an expiation involves giving each indigent person half a sa' of the staple food of the land, and this should be uncooked. It is permissible to cook food for sixty destitute persons and gather them to eat it. However, giving food to a poor family that consists of fewer than sixty individuals is not sufficient. Nevertheless, it is permissible to give half a sa' to a single indigent person from each expiation if there are multiple expiations.
