According to the well-known Sunni scholar Ibne Jawzi after sometime Abu Bakr decided to return Fadak to Hazrat Fatima (S A) and even wrote instruct to that effect.
However, Omar Bin Khattab tore away those instructions saying to Abu Bakr: “With what will you spend on the Muslims if the Arabs decided to fight with you?”
Hazrat Fatima (S.A) therefore went home empty handed. She never talked with Abu Baqr and Umar again till she died. It is interesting to note that although Fadak was taken away from her on the grounds that it belonged to the State, it came to be treated like it was a personal property of the rulers who pretended to be the successors of the Prophet.
For example, during the rulership of Othman, the Third caliph, he gave Fadak to Marwan his son-in-law. During the times of Muawia, Fadak was jointly owned by Marwan, Amr Bin Othman and Yezid Bin Muawiya. But when Marwan became the Ruler he owned it all alone.
His son Abdul Aziz inherited it from him. When Abdul Aziz died, Fadak passes to his son Omar who gave it to the grand-grand children of Hazrat Fatima (S.A). The Ummaya King who came after Omar Bin Abdul Aziz snatched it from Bani Fatima and it remained with Bani Umayyah until when Bani Abbas came in power.
The first Bani Abbas Ruler, Saffah, gave Fadak to Abdullah Bin Hasan (a grand-grand child of Imam Hasan). The second Ruler Mansur Dawanaki took it back. His son Mahdi gave it back to the descendants of Hazrat Fatima (S.A).
Harun Rashid took it back but his son Mammoon returned it to the descendants of Hazrat Fatima (S.A). Mutawakil again took it back. The present Saudi rulers have totally destroyed Fadak and it has been removed from the map.
