Muwatta Imam Malik 628

Yahya related to me from Malik from Zayd ibn Aslam from lyad ibn Abdullah ibn Sad ibn Abi Sarh al-Amiri that he had heard Abu Said al- Khudri say, "We used to pay the zakat al-fitr with a sa of wheat, or a sa of barley, or a sa of dates, or a sa of dried sour milk, or a sa of raisins, using the sa of the Prophet, may Allah bless him and grant him peace

Maliksaid, "Payment of all types of kaffara, of zakat al-fitr and of the zakat on grains for which a tenth or a twentieth is due, is made using the smaller mudd, which is the mudd of the Prophet, may Allah bless him and grant him peace, except in the case of dhihar divorce, when the kaffara is paid using the mudd of Hisham, which is the larger mudd." Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to send the zakat al-fitr to the one with whom it was collected together two or three days before the day of breaking the fast

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, made the zakat of breaking the fast at the end of Ramadan obligatory on every muslim, whether freeman or slave, male or female, and stipulated it as a sa' of dates or a sa' of barley
