عَنْ سُوَيْدِ بْنِ غَفَلَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: تَانَا مُصَدِّقُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ فَجَلَسْتُ لَهُ فَسَمِعْتُهُ وَهُوَ يَقُولُ: إِنَّ فِي عَهْدِي أَنْ لَا أَخُذَ مِنْ رَاضِعِ لَبَنٍ، وَلَا يُجْمَعُ بَيْنَ مُتَفَرِّقٍ وَلَا يُفَرَّقُ بَيْنَ مُجْتَمِعٍ وَأَتَاهُ رَجُلٌ بِنَاقَةٍ كَوْمَاءَ، فَقَالَ خُذْهَا فَأَبَى أَنْ يَأْخُذَهَا
Sayyiduna Suwaid bin Ghaflah رضي الله عنه narrates: The collector of zakat sent by the Messenger of Allah صلى الله عليه وآله وسلم came to us. I went to him, and he said: It is my responsibility that I do not take a suckling animal. (Secondly,) neither should separate herds be gathered together to avoid zakat, nor should a gathered herd be separated. Meanwhile, a man brought a tall, splendid she-camel with a prominent hump, but he refused to accept it.
