Muwatta Imam Malik Book of Zakat, Hadith 1

Yahya related to me from Malik from Amr ibn Yahya al-Mazini that his father said that he had heard Abu Said al-Khudri say that the Messenger of Allah ﷺ said, "There is no zakat on less than five camels, there is no zakat on less than five awaq (two hundred dirhams of pure silver) and there is no zakat on less than five awsuq (three hundred sa)."

حَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَمْرِو بْنِ يَحْيَى الْمَازِنِيِّ، عَنْ أَبِيهِ، أَنَّهُ قَالَ سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ، يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ : " لَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ صَدَقَةٌ " .
