The Prophet ﷺ said, "There is no zakat on fewer than five camels, no zakat on less than five awqiyyah of silver, and no zakat on less than five wasqs of produce."
حدثنا قتيبة حدثنا عبد العزيز بن محمد عن عمرو بن يحيى المازني عن أبيه
أن النبي ﷺ قال ليس فيما دون خمس ذود صدقة وليس فيما دون خمس أواق صدقة وليس فيما دون خمسة أوسق صدقة
Agreed upon, and Bukhari narrated it in the Book of Zakat, Chapter on the Zakat of Silver, no. 1447, and Muslim in the Book of Zakat, no. 979, from the hadith of Amr bin Yahya, with the same wording.There is also a version on this topic from Abu Hurairah [Ahmad: 2/402], Ibn Umar [Ahmad: 2/92], Jabir [Muslim, no. 980], and Abdullah bin Amr [Daraqutni: 2/93].
