It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), he says: In the time of the Messenger of Allah (peace and blessings be upon him), we used to give one sa’ each of barley, dates, raisins, and cheese as Sadaqat al-Fitr. But when Sayyiduna Muawiyah (may Allah be pleased with him) came (during his time for Hajj or Umrah), Syrian wheat had also arrived at that time. He expressed the opinion that one mudd of wheat is equivalent to two mudd of the other items.

(Second chain) It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), he says: When the Messenger of Allah (peace and blessings be upon him) was among us, we used to give one sa’ each of food, dates, barley, raisins, and cheese as Sadaqat al-Fitr, until Sayyiduna Muawiyah (may Allah be pleased with him) came to us.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) made it obligatory to give one sa’ of dates or barley as Sadaqat al-Fitr on every male and female, free and slave. Later, people considered half a sa’ of wheat to be equivalent to one sa’ of these items. Imam Nafi’ says: Sayyiduna Ibn Umar (may Allah be pleased with him) used to give dates as Sadaqat al-Fitr, but in one year there was a shortage of dates, so he gave barley.
