The amount to be given to the poor person in wheat and other items

Question:
May Allah reward you. This questioner requests a re-explanation of the author's statement: "Nothing less than a mudd (a quarter of a sa') of wheat, or less than two mudds of anything else, is sufficient for each person to whom zakah may be given."

Answer:
The amount to be given to the poor person is clear: a quarter of a sa' of wheat, and half a sa' of anything else, because a sa' is four mudds. It is necessary that the person receiving it be one to whom it is valid to give zakah. Kaffarah (expiation) is like zakah in that it is not permissible to give it to anyone other than the poor; it is not given to a rich person.
