Muwatta Malik, Book 17, Hadith 1 (USC-MSA) ⓘ

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, may Allah bless him and grant him peace, 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 صلى الله عليه وسلم ‏:‏ ‏ "‏ لَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ، وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ صَدَقَةٌ ‏" ‏ ‏.‏
