Sahih al-Bukhari · Book 64: Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi) · Prophet’s (saws) dealing with the people of Khaibar
Narrated `Abdullah:
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا جُوَيْرِيَةُ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ أَعْطَى النَّبِيُّ صلى الله عليه وسلم خَيْبَرَ الْيَهُودَ أَنْ يَعْمَلُوهَا وَيَزْرَعُوهَا، وَلَهُمْ شَطْرُ مَا يَخْرُجُ مِنْهَا.
The Prophet (ﷺ) gave (the land of) Khaibar to the Jews (of Khaibar) on condition that they would work on it and cultivate it and they would have half of its yield.
