Sahih al-Bukhari, Hadith 2499 ⓘ
Narrated `Abdullah: Allah's Messenger rented the land of Khaibar to the Jews on the condition that they would work on it and cultivate it and take half of its yield.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ بْنُ أَسْمَاءَ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ أَعْطَى رَسُولُ اللَّهِ صلى الله عليه وسلم خَيْبَرَ الْيَهُودَ أَنْ يَعْمَلُوهَا وَيَزْرَعُوهَا وَلَهُمْ شَطْرُ مَا يَخْرُجُ مِنْهَا.
