Narrated `Abdullah bin `Umar:
The Prophet (s.a.w.a.) concluded a contract with the people of Khaibar to utilize the land on the condition that half the products of fruits or vegetation would be their share. The Prophet (s.a.w.a.) used to give his wives one hundred Wasqs each, eighty Wasqs of dates and twenty Wasqs of barley. (When `Umar became the Caliph) he gave the wives of the Prophet (s.a.w.a.) the option of either having the land and water as their shares, or carrying on the previous practice. Some of them chose the land and some chose the Wasqs, and `Aisha chose the land.
Ibn Umar (Allah be pleased with them) reported:
Allah's Messenger (s.a.w.a.) handed over the land of Khaibar (on the condition) of the share of produce of fruits and harvest, and he also gave to his wives every year one hundred wasqs: eighty wasqs of dates and twenty wasqs of barley. When 'Umar became the caliph he distributed the (lands and trees) of Khaibar, and gave option to the wives of Allah's Apostle (s.a.w.a.) to earmark for themselves the land and water or stick to the wasqs (that they got) every year. They differed in this matter. Some of them opted for land and water, and some of them opted for wasqs every year. 'A'isha and Hafsa were among those who opted for land and water.
It has been narrated by 'Urwa b Zubair on the authority of 'A'isha, wife of the Prophet (s.a.w.a.), that Fatima, daughter of the Messenger of Allah (s.a.w.a.), requested Abu Bakr, after the death of the Messenger of Allah (may peace he upon him), that he should set apart her share from what the Messenger of Allah (s.a.w.a.) had left from the properties that God had bestowed upon him. Abu Bakr said to her:
The Messenger of Allah (s.a.w.a.) said:" We do not have any heirs; what we leave behind is Sadaqa (charity)." The narrator said: She (Fatima) lived six months after the death of the Messenger of Allah (s.a.w.a.) and she used to demand from Abu Bakr her share from the legacy of the Messenger of Allah (s.a.w.a.) from Khaibar, Fadak and his charitable endowments at Medina. Abu Bakr refused to give her this, and said: I am not going to give up doing anything which the Messenger of Allah (s.a.w.a.) used to do. I am afraid that it I go against his instructions in any matter I shall deviate from the right course. So far as the charitable endowments at Medina were concerned, 'Umar handed them over to 'Ali and Abbas, but 'Ali got the better of him (and kept the property under his exclusive possession). And as far as Khaibar and Fadak were concerned 'Umar kept them with him, and said: These are the endowments of the Messenger of Allah (s.a.w.a.) (to the Umma). Their income was spent on the discharge of the responsibilities that devolved upon him on the emergencies he had to meet. And their management was to be in the hands of one who managed the affairs (of the Islamic State). The narrator said: They have been managed as such up to this day.
‘Abd Allah bin ‘Umar reported that ‘Umar said “When Khaibar was conquered, the Jews asked the Apostle of Allaah(s) to confirm that they would do all the cultivation and have half the produce. The Apostle of Allaah(s) 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 Apostle of Allaah(s) would take the fifth. The Apostle of Allaah(s) 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 (s.a.w.a.) 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).
