English translation
3410. It was narrated from 'Umar bin Ayyūb that Ja'far bin Burqān narrated from Maimūn bin Mihrān, from Miqsam, from Ibn 'Abbās, who said: "The Messenger of Allāh ﷺ conquered Khaibar and stipulated that the land and all the yellow and white (i.e., gold and silver) would belong to him. The people of Khaibar said: 'We know the land better than you, so give it to us on the basis that you will have half of the yield and we will have half.'" And he said that he gave it to them on that basis. When the time came to harvest the palm trees, he sent 'Abdullāh bin Rawāhah to assess the likely yield of the palm trees, which is what the people of Al-Madinah call Al-Khars (estimation). He said: "For this tree, such and such (an amount)." They said; "You are demanding too much of us, O Ibn Rawāhah!" He said: "I take responsibility for the assessment and I will give you half of what I said." They said: "This is fair, and fairness is what heaven and earth are based on." They said: "We agree to take what you say." (Hasan)
