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  

ʿUmar expelled the Jews and the Christians from Hijaz. When Messenger of Allah ﷺ had conquered Khaibar, he wanted to expel the Jews from it as its land became the property of Allah, His Apostle, and the Muslims. Messenger of Allah ﷺ intended to expel the Jews but they requested him to let them stay there on the condition that they would do the labor and get half of the fruits. Messenger of Allah ﷺ told them, "We will let you stay on thus condition, as long as we wish." So, they (i.e. Jews) kept on living there until ʿUmar forced them to go towards Taima' and Ariha'.  

أَنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ أَجْلَى الْيَهُودَ وَالنَّصَارَى مِنْ أَرْضِ الْحِجَازِ وَكَانَ رَسُولُ اللَّهِ ﷺ لَمَّا ظَهَرَ عَلَى خَيْبَرَ أَرَادَ إِخْرَاجَ الْيَهُودِ مِنْهَا وَكَانَتِ الأَرْضُ حِينَ ظَهَرَ عَلَيْهَا لِلَّهِ وَلِرَسُولِهِ ﷺ وَلِلْمُسْلِمِينَ وَأَرَادَ إِخْرَاجَ الْيَهُودِ مِنْهَا فَسَأَلَتِ الْيَهُودُ رَسُولَ اللَّهِ ﷺ لِيُقِرَّهُمْ بِهَا أَنْ يَكْفُوا عَمَلَهَا وَلَهُمْ نِصْفُ الثَّمَرِ فَقَالَ لَهُمْ رَسُولُ اللَّهِ ﷺ: «نُقِرُّكُمْ بِهَا عَلَى ذَلِكَ مَا شِئْنَا۔» فَقَرُّوا بِهَا حَتَّى أَجْلاَهُمْ عُمَرُ إِلَى تَيْمَاءَ وَأَرِيحَاءَ۔
