وَحَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ السَّعْدِيُّ، حَدَّثَنَا عَلِيٌّ، - وَهُوَ ابْنُ مُسْهِرٍ - أَخْبَرَنَا عُبَيْدُ، اللَّهِ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ أَعْطَى رَسُولُ اللَّهِ صلى الله عليه وسلم خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْ ثَمَرٍ أَوْ زَرْعٍ فَكَانَ يُعْطِي أَزْوَاجَهُ كَلَّ سَنَةٍ مِائَةَ وَسْقٍ ثَمَانِينَ وَسْقًا مِنْ تَمْرٍ وَعِشْرِينَ وَسْقًا مِنْ شَعِيرٍ فَلَمَّا وَلِيَ عُمَرُ قَسَمَ خَيْبَرَ خَيَّرَ أَزْوَاجَ النَّبِيِّ صلى الله عليه وسلم أَنْ يُقْطِعَ لَهُنَّ الأَرْضَ وَالْمَاءَ أَوْ يَضْمَنَ لَهُنَّ الأَوْسَاقَ كُلَّ عَامٍ فَاخْتَلَفْنَ فَمِنْهُنَّ مَنِ اخْتَارَ الأَرْضَ وَالْمَاءَ وَمِنْهُنَّ مَنِ اخْتَارَ الأَوْسَاقَ كُلَّ عَامٍ فَكَانَتْ عَائِشَةُ وَحَفْصَةُ مِمَّنِ اخْتَارَتَا الأَرْضَ وَالْمَاءَ ‏.‏
