Section : Things on which Zakat must be Paid.

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."
