Chapter 27: Who Pays the Zakat al-Fitr
Muwatta Malik 649
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 ﷺ except in the case of dhihar divorce, when the kaffara is paid using the mudd of Hisham, which is the larger mudd."
