The Prophet ﷺ said, "There is no zakat on less than five wasq, no zakat on less than five uqiyyah, and no zakat on less than five camels."
عن النبي ﷺ قال: ليس فيما دون خمسة أوسق صدقة، ولا فيما دون خمس أواق صدقة، ولا فيما دون خمس ذود صدقة.
Imam Ahmad narrated it (9221, 9232) through two routes from Abdullah bin Mubarak, who said, "Mamar told us," who said, "Suhayl bin Abu Salih told me, from his father, from Abu Hurairah," and he mentioned the hadith. Its isnad is sahih.
