Sunan Abi Dawud, 1580
hasan· Al-Albani

Suwaid bin Ghaflah reported The collector of the Prophet (ﷺ) came to us. I caught hold of his hand and read in the document that the goods were not to be combined nor were they to be separated for fear of zakat. There is no mention of milch animals in this tradition.

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ الْبَزَّازُ، حَدَّثَنَا شَرِيكٌ، عَنْ عُثْمَانَ بْنِ أَبِي زُرْعَةَ، عَنْ أَبِي لَيْلَى الْكِنْدِيِّ، عَنْ سُوَيْدِ بْنِ غَفَلَةَ، قَالَ أَتَانَا مُصَدِّقُ النَّبِيِّ صلى الله عليه وسلم فَأَخَذْتُ بِيَدِهِ وَقَرَأْتُ فِي عَهْدِهِ ‏"‏ لاَ يُجْمَعُ بَيْنَ مُفْتَرِقٍ وَلاَ يُفَرَّقُ بَيْنَ مُجْتَمِعٍ خَشْيَةَ الصَّدَقَةِ ‏"‏ ‏.‏ وَلَمْ يَذْكُرْ ‏"‏ رَاضِعَ لَبَنٍ ‏"‏ ‏.‏
