Hadith 7:158
Muslim has:
Allah's Messenger (ﷺ) handed over to the Jews of Khaibar, the palm-trees and the land of Khaibar, on condition that they should employ their own resources in working on it and keep half of its produce.
وَلِمُسْلِمٍ: { أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -دَفَعَ إِلَى يَهُودِ خَيْبَرَ نَخْلَ خَيْبَرَ وَأَرْضَهَا عَلَى أَنْ يَعْتَمِلُوهَا مِنْ أَمْوَالِهِمْ, وَلَهُ شَطْرُ ثَمَرِهَا }
