The Prophet ﷺ concluded a contract with the people of Khaibar to utilize the land on the condition that half the products of fruits or vegetation would be their share. The Prophet ﷺ used to give his wives one hundred Wasqs each, eighty Wasqs of dates and twenty Wasqs of barley. (When ʿUmar became the Caliph) he gave the wives of the Prophet ﷺ the option of either having the land and water as their shares, or carrying on the previous practice. Some of them chose the land and some chose the Wasqs, and ʿAisha chose the land.  

أَخْبَرَهُ أَنَّ النَّبِيَّ ﷺ عَامَلَ خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْهَا مِنْ ثَمَرٍ أَوْ زَرْعٍ فَكَانَ يُعْطِي أَزْوَاجَهُ مِائَةَ وَسْقٍ ثَمَانُونَ وَسْقَ تَمْرٍ وَعِشْرُونَ وَسْقَ شَعِيرٍ فَقَسَمَ عُمَرُ خَيْبَرَ فَخَيَّرَ أَزْوَاجَ النَّبِيِّ ﷺ أَنْ يُقْطِعَ لَهُنَّ مِنَ الْمَاءِ وَالأَرْضِ أَوْ يُمْضِيَ لَهُنَّ فَمِنْهُنَّ مَنِ اخْتَارَ الأَرْضَ وَمِنْهُنَّ مَنِ اخْتَارَ الْوَسْقَ وَكَانَتْ عَائِشَةُ اخْتَارَتِ الأَرْضَ  

Messenger of Allah ﷺ handed over the land of Khaibar (on the condition) of the share of produce of fruits and harvest, and he also gave to his wives every year one hundred wasqs: eighty wasqs of dates and twenty wasqs of barley. When 'Umar became the caliph he distributed the (lands and trees) of Khaibar, and gave option to the wives of Allah's Apostle ﷺ to earmark for themselves the land and water or stick to the wasqs (that they got) every year. They differed in this matter. Some of them opted for land and water, and some of them opted for wasqs every year. 'A'isha and Hafsa were among those who opted for land and water.  

أَعْطَى رَسُولُ اللَّهِ ﷺ 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 ﷺ 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  

[Machine] Allah ﷺ treated the people of Khaybar with half of what comes out of crops or fruits. He used to give his wives a hundred measures of dates, eighty measures of barley, and twenty measures of wheat every year. When Umar ibn al-Khattab became the ruler, he distributed Khaybar and gave the Prophet's wives the choice between having land and water or receiving a fixed annual income. They disagreed, and some of them chose the land and water, while others chose the fixed income. Aisha and Hafsah chose to have land and water. This narration is mentioned in the hadith of Abu Damrah and in the narration of Ali ibn Mus-hir.  

اللهِ ﷺ عَامَلَ أَهْلَ خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْ زَرْعٍ أَوْ ثَمَرٍ قَالَ فَكَانَ يُعْطِي أَزْوَاجَهُ كُلَّ عَامٍ مِنْهُ مِائَةَ وَسْقٍ ثَمَانِينَ وَسْقًا تَمْرًا وَعِشْرِينَ وَسْقًا شَعِيرًا فَلَمَّا كَانَ عُمَرُ ؓ قَسَمَ خَيْبَرَ فَخَيَّرَ أَزْوَاجَ النَّبِيِّ ﷺ أَنْ يَقْطَعَ لَهُنَّ مِنَ الْأَرْضِ وَالْمَاءِ أَوْ يَضْمَنَ لَهُنَّ الْوُسُوقَ كُلَّ عَامٍ فَاخْتَلَفْنَ فَمِنْهُنَّ مَنِ اخْتَارَ الْأَرْضَ وَالْمَاءَ وَمِنْهُنَّ مَنِ اخْتَارَ الْوُسُوقَ فَكَانَتْ عَائِشَةُ وَحَفْصَةُ ؓ مِمَّنِ اخْتَارَتَا الْأَرْضَ وَالْمَاءَ لَفْظُ حَدِيثِ أَبِي ضَمْرَةَ وَفِي رِوَايَةِ عَلِيِّ بْنِ مُسْهِرٍ أَعْطَى رَسُولُ اللهِ ﷺ خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْ تَمْرٍ أَوْ زَرْعٍ ثُمَّ ذَكَرَ الْبَاقِيَ بِمَعْنَاهُ
