Bulugh al-Maram

Book 7: Business Transactions
وَلِمُسْلِمٍ: { أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-دَفَعَ إِلَى يَهُودِ خَيْبَرَ نَخْلَ خَيْبَرَ وَأَرْضَهَا عَلَى أَنْ يَعْتَمِلُوهَا مِنْ أَمْوَالِهِمْ, وَلَهُ شَطْرُ ثَمَرِهَا } 1‏ .‏
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.
