Sunan of Abu Dawood Book 20, Hadith 3014

حَدَّثَنَا مُحَمَّدُ بْنُ مِسْكِينٍ الْيَمَامِيُّ، حَدَّثَنَا يَحْيَى بْنُ حَسَّانَ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ بُشَيْرِ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمَّا أَفَاءَ اللَّهُ عَلَيْهِ خَيْبَرَ قَسَمَهَا سِتَّةً وَثَلاَثِينَ سَهْمًا جَمْعًا فَعَزَلَ لِلْمُسْلِمِينَ الشَّطْرَ ثَمَانِيَةَ عَشَرَ سَهْمًا يَجْمَعُ كُلُّ سَهْمٍ مِائَةً النَّبِيُّ صلى الله عليه وسلم مَعَهُمْ لَهُ سَهْمٌ كَسَهْمِ أَحَدِهِمْ وَعَزَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم ثَمَانِيَةَ عَشَرَ سَهْمًا وَهُوَ الشَّطْرُ لِنَوَائِبِهِ وَمَا يَنْ��ِلُ بِهِ مِنْ أَمْرِ الْمُسْلِمِينَ فَكَانَ ذَلِكَ الْوَطِيحَ وَالْكُتَيْبَةَ وَالسُّلاَلِمَ وَتَوَابِعَهَا فَلَمَّا صَارَتِ الأَمْوَالُ بِيَدِ النَّبِيِّ صلى الله عليه وسلم وَالْمُسْلِمِينَ لَمْ يَكُنْ لَهُمْ عُمَّالٌ يَكْفُونَهُمْ عَمَلَهَا فَدَعَا رَسُولُ اللَّهِ صلى الله عليه وسلم الْيَهُودَ فَعَامَلَهُمْ ‏.‏
