It was narrated that Abu Sa'eed Al-Khudri said: "We used to pay Zakatul-Fitr when the Messenger of Allah P.B.U.H was among us, one Sit of food, one Sa' of dates, one sa' of barley, one Sa' of sun-baked cottage cheese, one Sa' of raisins. We continued to do that until Mu'awiyah came to us in AI-Madinah. One of the things he said to the people was: 'I think that two Mudd wheat from Sham is equivalent to one sa' of this (i.e., dates).' So the people followed that." Abu Sa'eed said: "I will continue to pay it as I used to pay it at the time of the Messenger of Allah P.B.U.H, for as long as Llive." (sahih)
