What is the amount of zakat al-fitr in a sa' or in kilograms?

Question : Regarding zakat al-fitr, Honorable Shaykh, the questioner says: What is its amount in a sa' or in kilograms?

Answer : The amount of zakat al-fitr is a sa' of food. This can be wheat, rice, dates, raisins, or other things that people eat. This is based on the statement of Abu Sa'id al-Khudri (may Allah be pleased with him): "We used to give it in the time of the Prophet (peace and blessings be upon him) as a sa' of food." As for calculating it by weight, that varies, because some food is heavy in weight and some is light. It cannot be determined by weight because it is determined by the Shari'ah.
