"The Messenger of Allah enjoined Sadaqatul Fitr, a Sa' of barley or a Sa of dates or a Sa' of cottage cheese."
Sunan an-Nasa'i Book 23, Hadith 77
← Previous Hadith I heard Ibn 'Abbas deliver a Khutbah from your Minbar - meaning the Minbar in Al-Basrah - saying: 'Sadaqatul Fitr is a Sa' of food." (Sahih) Abu 'Abdur-Rahman (An-Nasa'i) said: This is the most reliable of the three.

Sunan an-Nasa'i Book 23, Hadith 76 Next Hadith → "We used to pay Zakaul Fitr when the Messenger of Allah was among us; a Sa' of food, or a Sa' of barley, or a Sa' of dates, or a Sa' of raisins, or a Sa of cottage cheese."
