أَخْبَرَنَا عَمْرُو بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ مَحْبُوبٍ، قَالَ حَدَّثَنَا هُشَيْمٌ، قَالَ أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ خَالِدِ بْنِ أَبِي عِمْرَانَ، عَنْ حَنَشٍ الصَّنْعَانِيِّ، عَنْ فَضَالَةَ بْنِ عُبَيْدٍ، قَالَ أَصَبْتُ يَوْمَ خَيْبَرَ قِلاَدَةً فِيهَا ذَهَبٌ وَخَرَزٌ فَأَرَدْتُ أَنْ أَبِيعَهَا فَذُكِرَ ذَلِكَ لِلنَّبِيِّ صلى الله عليه وسلم فَقَالَ " افْصِلْ بَعْضَهَا مِنْ بَعْضٍ ثُمَّ بِعْهَا " .
