Allah's Messenger (ﷺ) said, "No Zakat is imposed on less than five Awsuq of dates; no Zakat is imposed on less than five Awaq of silver, and no Zakat is imposed on less than five camels."
Sahih al-Bukhari Book 24, Hadith 61
← Previous Hadith When Allah's Messenger (ﷺ) (p.b.u.h) sent Mu`adh to Yemen, he said (to him), "YOU are going to people of a (Divine) Book. First of all invite them to worship Allah (alone) and when they come to know Allah, inform them that Allah has enjoined on them, five prayers in every day and night; and if they start offering these prayers, inform them that Allah has enjoined on them, the Zakat. And it is to be taken from the rich amongst them and given to the poor amongst them; and if they obey you in that, take Zakat from them and avoid (don't take) the best property of the people as Zakat."

Sahih al-Bukhari Book 24, Hadith 60 Next Hadith → Once I went to him (the Prophet (ﷺ) ) and he said, "By Allah in Whose Hands my life is (or probably said, 'By Allah, except Whom none has the right to be worshipped) whoever had camels or cows or sheep and did not pay their Zakat, those animals will be brought on the Day of Resurrection far bigger and fatter than before and they will tread him under their hooves, and will butt him with their horns, and (those animals will come in circle): When the last does its turn, the first will start again, and this punishment will go on till Allah has finished the judgments amongst the people."
