Narrated Abdullah ibn Umar: Umar said: The Messenger of Allah ﷺ had transaction with the Jews of Khaybar on condition that we should expel them when we wish. If anyone has property (with them), he should take it back, for I am going to expel the Jews. So he expelled them.

Abdullah bin Umar reported that Umar said “When Khaibar was conquered, the Jews asked the Messenger of Allah ﷺ to confirm that they would do all the cultivation and have half the produce. The Messenger of Allah ﷺ said “I shall confirm you on that condition as long as we wish. So they were confirmed on that (condition). The dates from half the produce of Khaibar were divided into a number of portions. The Messenger of Allah ﷺ would take the fifth. The Messenger of Allah ﷺ used to contribute from the fifth one hundred wasqs of dates and twenty wasqs of wheat to each of his wives. When Umar intended to expel the Jews from Khaibar he sent a message to the wives of the Prophet ﷺ and said to them “If any of you wishes that I divide the palm trees for her by their assessment that amounts one hundred wasqs (of dates) and to her belongs their root, their land and their water and (likewise) twenty wasqs from the produce of the cultivated land by assessment, I shall (do that). And if any of you wishes that we take out her portion from the fifth, we shall do (that).

Ibn Shihab said “It has reached me that the Messenger of Allah ﷺ conquered Khaibar by force. Its inhabitants who came down (from their fortress) for expulsion came down after fighting. ”

Narrated Ibn Umar: The Messenger of Allah ﷺ made an agreement with the people of Khaibar to work and cultivate in return for half of the fruits or produce.

Narrated Ibn Umar: The Prophet ﷺ handed over the Jews of Khaibar the palm trees and the land of Khaibar on condition that they should employ what belonged to them in working on them, and that he should have half of the fruits.

Narrated Ibn Abbas: The Messenger of Allah ﷺ conquered Khaibar, and stipulated that all the land, gold and silver would belong to him. The people of Khaibar said: we know the land more than you ; so give it to us on condition that you should have half of the produce and we would have the half. He then gave it to them on that condition. When the time of picking the fruits of the palm-trees came, he sent Abdullah bin Rawahah to them, and he assessed the among of the fruits of the palm-trees. This is what the people of Madina call khars (assessment). He used to say: In these palm-trees there is such-and-such amount (of produce). They would say: You assessed more to us, Ibn Rawahah (than the real amount). He would say: I first take the responsibility of assessing the fruits of the palm-trees and give you half of (the amount) I said. They would say: This is true, and on this (equity) stand the heavens and the earth. We agreed that we should take (the amount which) you said.

Narrated Jabir ibn Abdullah: When Allah bestowed Khaybar on His Prophet ﷺ as fay (as a result of conquest without fighting), the Messenger of Allah ﷺ allowed (them) to remain there as they were before, and apportioned it between him and them. He then sent Abdullah ibn Rawahah who assessed (the amount of dates) upon them.
