Sunan Ibn Majah 1801
It was narrated that:
Suwaid bin Ghafalah said: ”The Zakah collector of the Prophet came to us, and I took him by the hand and read in his order: 'Do not gather separate herds and do not separate herd for fear of Sadaqah'. A man brought him a huge, fat she-camel, but he refused to accept it. So he brought him another of lower quality and he accepted it. He said: 'What land would shelter me, if I came to the Messenger of Allah having taken the nest of a Muslim man's camels?' ”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا شَرِيكٌ، عَنْ عُثْمَانَ الثَّقَفِيِّ، عَنْ أَبِي لَيْلَى الْكِنْدِيِّ، عَنْ سُوَيْدِ بْنِ غَفَلَةَ، قَالَ جَاءَنَا مُصَدِّقُ النَّبِيِّ ـ صلى الله عليه وسلم ـ فَأَخَذْتُ بِيَدِهِ وَقَرَأْتُ فِي عَهْدِهِ لاَ يُجْمَعُ بَيْنَ مُتَفَرِّقٍ وَلاَ يُفَرَّقُ بَيْنَ مُجْتَمِعٍ خَشْيَةَ الصَّدَقَةِ ‏.‏ فَأَتَاهُ رَجُلٌ بِنَاقَةٍ عَظِيمَةٍ مُلَمْلَمَةٍ فَأَبَى أَنْ يَأْخُذَهَا فَأَتَاهُ بِأُخْرَى دُونَهَا فَأَخَذَهَا وَقَالَ أَىُّ أَرْضٍ تُقِلُّنِي وَأَىُّ سَمَاءٍ تُظِلُّنِي إِذَا أَتَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ وَقَدْ أَخَذْتُ خِيَارَ إِبِلِ رَجُلٍ مُسْلِمٍ ‏.‏
