It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that in the blessed era of the Prophet (peace and blessings be upon him), we used to give one sa’ of dates or barley, or cheese, or raisins as Sadaqat al-Fitr. Then, during the time of Hazrat Muawiyah (may Allah be pleased with him), wheat became available, and his opinion was that its one mudd is equal to two (of the others).
