BAYHAQI 11621:
from Ibn ʿUmar —
[Machine] The Messenger of Allah ﷺ worked with the people of Khaybar in exchange for half of what is produced from the fruits or crops. Anas Ibn Malik reported that Abu Bakr ibn Yazdad narrated to us, saying that Abu Ishaq al-Isfara'ini, the Imam, informed us that Muhammad ibn Ayyub al-Razi narrated to us, saying that Musaddad narrated to us, saying that Yahya mentioned it in a similar way, except that he said "in exchange for half of what comes out of it from fruits or crops."

عن ابن عمر —
أَنَّ رَسُولَ اللهِ ﷺ عَامَلَ أَهْلَ خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْ ثَمَرٍ أَوْ زَرْعٍ 11622 وَأَخْبَرَنَا أَبُو إِسْحَاقَ الِإسْفَرَايِينِيُّ الْإِمَامُ أنبأ أَبُو بَكْرِ بْنُ يَزْدَادَ ثنا مُحَمَّدُ بْنُ أَيُّوبَ الرَّازِيُّ ثنا مُسَدَّدٌ ثنا يَحْيَى فَذَكَرَهُ بِنَحْوِهِ إِلَّا أَنَّهُ قَالَ بِشَطْرِ مَا يَخْرُجُ مِنْهَا مِنْ ثَمَرٍ أَوْ زَرْعٍ
