The Messenger of Allah ﷺ said, "There is no zakat on fewer than five camels, no zakat on less than five awqiyah of silver, and no zakat on less than five wasq of produce."
قال رسول الله ﷺ: ليس فيما دون خمس ذود صدقة، وليس فيما دون خمسة أواق صدقة، وليس فيما دون خمسة أوسق صدقة.
Malik related it in the Book of Zakat (1), from Amr bin Yahya Mazini, from his father, that he heard Abu Saeed Khudri say (then he mentioned the hadith). Bukhari related it in the Book of Zakat (1447), from Abdullah bin Yusuf, who said, Malik informed us. Muslim related it in the Book of Zakat (979) through another route, from Amr bin Yahya, with the same wording.As for his saying "khams dhawd" (five camels), this is by attaching "dhawd" to "khams" in a genitive construction. It has also been narrated with "khams" taking nunation, in which case "dhawd" stands as an appositive to it. Linguistically, "dhawd" refers to a number of camels ranging from three to ten, and it has no singular form derived from its own root, rather the singular is expressed as "baeer." So his saying "khams dhawd" is like saying "five camels" (khamsah abira), "five camels" (khamsah jimal), "five she-camels" (khams nuwaq), and the like.As for his saying "khams awaq" with nunation, in another narration it appears as "awaqi" with the ya retained, and both are sahih. The "uqiyyah" is spelled with a dammah on the hamzah and a doubled ya, and its plural forms are "awaqi" (with the ya either doubled or shortened) and "awaq" (with the ya dropped). The scholars of hadith, jurisprudence, and language are unanimous that the legal uqiyyah equals forty dirhams, and this is the uqiyyah of Hijaz.Qadi Iyad said, It cannot be valid for the uqiyyah and the dirhams to have been unknown in the time of the Prophet ﷺ, given that he made zakat obligatory in specific quantities of them, and that transactions and marriage contracts were conducted using them, as is established in the sahih hadiths.As for his saying "khamsah awsuq" (five wasqs), "awsuq" is the plural of "wasq," and there are two ways of pronouncing it, opening the waw, which is the well-known form, or putting a kasrah on it. Its original linguistic meaning is "load." A wasq equals sixty saa, so five wasqs amount to 60 x 5 = 300 saa. The measure of the Prophetic saa is two and a half kilograms. Accordingly, the weight of five wasqs comes to 300 x 2.5 = 750 kilograms.
