(20) باب كَمْ يُؤَدَّى فِي صَدَقَةِ الْفِطْرِ
Narrated Abu Sa'id al-Khudri:
I shall always pay one sa'. We used to pay during the lifetime of the Messenger of Allah (ﷺ) one sa' of dried dates or of barley, or of cheese, or of raisins. This is the version of Yahya. Sufyan added in his version: "or one sa' of flour." The narrator Hamid (ibn Yahya) said: The people objected to this (addition); Sufyan then left it. Abu Dawud said: This addition is a misunderstanding on the part of Ibn Uyainah.
