Yahya related to me from Malik from Muhammad ibn Abdullah ibn Abd
arRahman ibn Abi Sasaca al-Ansari from al-Mazini from his father from
Abu Said al-Khudri that the Messenger of Allah, may Allah bless him
and grant him peace, said, "There is no zakat on less than five awsuq
of dates, there is no zakat on less than five awaq of silver and there
is no zakat on less than five camels."
Muwatta Malik Book 17, Hadith 2
