Ayyad bin 'Abdullah bin Sa'd عياض بن عبد الله بن سعد بن أبي سرح · The Book of Zakah

"We used to fast on 'Ashura and give Zakatul-Fitr, and when the command to fast in Ramadan was revealed, and the command to give Zakah was revealed, we were neither commanded to give it, nor told not to do so, and we used to do it."

"The Messenger of Allah commanded us to give Sadaqatul Fitr before the command to give Zakah was revealed. When the command to give Zakah was revealed, he neither told us to do it, not told us not to do it, and we used to do it." (Sahih) Abu 'Abdur-Rahman (An-Nasai) said: Abu 'Ammar's name is 'Arib bin Humaid, and 'Amr bin Shurabbil's Kunyah is Abu Maisarah, and Salamah bin Kuhail contradicted Al-Hakam in his chain, and Al-Hakam is more reliable…

"Give Zakah of your fast." The people looked at one another, so he said: "Whoever is here from the people of Al-Madinah, get up and teach your brothers, for they do lnot know that this Zakah was enjoined by the Messenger of Allah upon every male and female, free and slave, a Sa' of barley or dates, or half a Sa' of wheat. "So they got up. (Da'if) Hisham contradicted him, he said: "From Muhammad bin Sirin."

"We used to pay Salaqatul Fitr when the Messenger of Allah was among us; a Sa' of food, or a Sa' of dates, or a Sa' of barley, or a Sa' of cottage cheese. We continued to do so until Mu'awiyah came from Ash-Sham and one of the things that he taught the people was when he said: I think that two Mudds of wheat from Ash-Sham are equivalent to a Sa' of this, So the people took to that."
