What happened to Fadak thereafter, was that Umar bin Abdul Aziz gave Fadak to Imam Muhammad Baqir (a.s.). It should be noted that among the Caliphs of Bani Umayyah, this is the only one who can be said to have humane qualities. The rest of the Caliphs’ rule was nightmare, or they were the ones whom humanness had not even touched. When this Caliph, Umar the second, restored Fadak to Ahlul Bayt, people told him: “You have taunted the first two Shaykhs (Caliphs).”1 In response the Caliph said: “The two Shaykhs had, by confiscating Fadak, opened a door of taunts for themselves.”
It should be remembered that Umar bin Abdul Aziz was among the last Caliphs of Bani Umayyah and it is a fact that he was very justice-loving among Bani Umayyah and it was because of his good and truth-loving nature that he restored Fadak to Ahlul Bayt. But in response to his just nature his community poisoned him. Truthfulness in the matter of Ahlul Bayt is not an easy thing. Such truth-telling involved a sure risk to life during the Caliphates of Bani Umayyah and Bani Abbas. But now since the British are ruling2, a risk to life is not more felt. Yet various harms are not totally ruled out.
Anyway, when the Caliphate went out of the hands of Bani Umayyah those Caliphs of Bani Abbas, who cared for the rights of Ahlul Bayt, like Mamoon, Motasim and Wathiq, had returned Fadak to the progeny of Lady Fatima. But then Mutawakkil, the Ahlul Bayt-hater (Nasibi) again snatched it from Ahlul Bayt and gave it to his barber. But Mutazz once again restored it to Fatima’s progeny. Then Motaqifa returned it to Ahlul Bayt but Muktafi again snatched it.
It is written in Sharh Ibn Abil Hadid on Pg. 493 that, “When Umar bin Abdul Aziz became the Caliph, he returned Fadak to the progeny of Hasan and according to another narration to the progeny of Zainul Aabideen and thus Fadak continuously remained in the hands of Bani Fatima but in his time, Yazeed Aatikaa snatched it.
Thereafter, it remained in the hands of the progeny of Marwan. Thereafter, Saffah, the Abbasid returned it to Abdullah bin Hasan, but Abu Ja’far Mansoor again snatched it. Then Mahdi Abbasi returned it to Bani Fatima. Then Moosa bin Mahdi and his brother Haroon Rashid confiscated it and it remained in the hands of Abbasids thereafter. Then Haroon Rashid returned it to Bani Fatima.
