Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: When the Messenger of Allah (peace and blessings be upon him) was with us, we used to give one sa' of grain, or one sa' of dates, or one sa' of barley, or one sa' of cheese, or one sa' of raisins as zakat al-fitr on behalf of every young and old, and slave, and this continued until after Hajj or 'Umrah when Sayyiduna Mu'awiyah (may Allah be pleased with him) came to us in Madinah and said: "In my opinion, two mudd of this Syrian wheat are equal to one sa' of dates." So the people adopted this (i.e., half a sa' of wheat as zakat al-fitr). Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: But I continue to give the same amount of zakat al-fitr as I used to give during the time of the Messenger of Allah (peace and blessings be upon him) (i.e., a full sa'). Imam Darimi (may Allah have mercy on him) said: In my opinion, zakat al-fitr should be given as one sa' of any of the mentioned items.
