[Machine] The Prophet ﷺ did not have workers to work on the dates and crops in Khaybar. So the Prophet ﷺ called the Jews of Khaybar and gave the land of Khaybar to them on the condition that they cultivate it and give half of its produce to the Messenger of Allah ﷺ and his companions. The Prophet ﷺ told them, "I grant you in it what Allah has granted you." The Messenger of Allah ﷺ used to send Abdullah ibn Rawahah to them, who would pollinate the palm trees when the first fruits became fragrant, before they were eaten. Then he would give the Jews the choice to take the fruits with or without pollination.  

لَمْ يَكُنْ لِلنَّبِيِّ ﷺ عُمَّالًا يَعْمَلُونَ بِهَا عَلَى نَخْلِ خَيْبَرَ وَزَرْعِهَا فَدَعَا النَّبِيُّ ﷺ يَهُودَ خَيْبَرَ فَدَفَعَ إِلَيْهِمْ خَيْبَرَ عَلَى أَنْ يَعْمَلُوهَا عَلَى النِّصْفِ فَيُؤَدُّونَهُ إِلَى رَسُولِ اللهِ ﷺ وَأَصْحَابِهِ وَقَالَ لَهُمُ النَّبِيُّ ﷺ «أُقِرُّكُمْ فِيهَا مَا أَقَرَّكُمُ اللهُ» فَكَانَ رَسُولُ اللهِ ﷺ يَبْعَثُ إِلَيْهِمْ عَبْدَ اللهِ بْنَ رَوَاحَةَ فَيَخْرُصُ النَّخْلَ حِينَ يَطِيبُ أَوَّلُ الثَّمَرِ قَبْلَ أَنْ يُؤْكَلَ مِنْهُ ثُمَّ يُخَيِّرُ الْيَهُودَ أَنْ يَأْخُذُوهَا بِذَلِكَ الْخَرْصِ أَوْ يَدْفَعُوهَا إِلَيْهِمْ بِذَلِكَ الْخَرْصِ
