bukhari:6955Muḥammad b. ʿAbdullāh al-Anṣārī from my father > Thumāmah b. ʿAbdullāh b. Anas > Anas

That Abu Bakr wrote for him, Zakat regulations which Messenger of Allah ﷺ had made compulsory, and wrote that one should neither collect various portions (of the property) nor divide the property into various portions in order to avoid paying Zakat.  

البخاري:٦٩٥٥حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الأَنْصَارِيُّ حَدَّثَنَا أَبِي حَدَّثَنَا ثُمَامَةُ بْنُ عَبْدِ اللَّهِ بْنِ أَنَسٍ أَنَّ أَنَسًا حَدَّثَهُ

أَنَّ أَبَا بَكْرٍ كَتَبَ لَهُ فَرِيضَةَ الصَّدَقَةِ الَّتِي فَرَضَ رَسُولُ اللَّهِ ﷺ وَلاَ يُجْمَعُ بَيْنَ مُتَفَرِّقٍ وَلاَ يُفَرَّقُ بَيْنَ مُجْتَمِعٍ خَشْيَةَ الصَّدَقَةِ

bukhari:1450Muḥammad b. ʿAbdullāh al-Anṣārī from my father > Thumāmah > Anas from my father

Abu Bakr wrote to me what was made compulsory by Messenger of Allah ﷺ and that was (regarding the payments of Zakat): Neither the property of different people may be taken together nor the joint property may be split for fear of (paying more, or receiving less) Zakat.  

البخاري:١٤٥٠حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الأَنْصَارِيُّ قَالَ حَدَّثَنِي أَبِي قَالَ حَدَّثَنِي ثُمَامَةُ أَنَّ أَنَسًا ؓ حَدَّثَهُ

أَنَّ أَبَا بَكْرٍ ؓ كَتَبَ لَهُ الَّتِي فَرَضَ رَسُولُ اللَّهِ ﷺ وَلاَ يُجْمَعُ بَيْنَ مُتَفَرِّقٍ وَلاَ يُفَرَّقُ بَيْنَ مُجْتَمِعٍ خَشْيَةَ الصَّدَقَةِ  

darimi:1670al-Aswad b. ʿĀmir > Sharīk

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. (Using translation from Abū Dāʾūd 1580)   

الدارمي:١٦٧٠أَخْبَرَنَا الْأَسْوَدُ بْنُ عَامِرٍ حَدَّثَنَا شَرِيكٌ عَنْ عُثْمَانَ الثَّقَفِيِّ عَنْ أَبِي لَيْلَى هُوَ الْكِنْدِيُّ عَنْ سُوَيْدِ بْنِ غَفَلَةَ قَالَ

أَتَانَا مُصَدِّقُ النَّبِيِّ ﷺ فَأَخَذْتُ بِيَدِهِ فَقَرَأْتُ فِي عَهْدِهِ «أَنْ لَا يُجْمَعَ بَيْنَ مُتَفَرِّقٍ وَلَا يُفَرَّقَ بَيْنَ مُجْتَمِعٍ خَشْيَةَ الصَّدَقَةِ»
