Fadak, Fatima and Abu baker

Fadak Belonged to Mohammad (PBUH). He gave it to her daughter Fatima (PBUH) as a gift (see e.g.??). It should have remained in her possession after he passed away. Even if it wasn't given as a gift, its ownership should have passed onto Fatima (PBUH) as inheritance as a personal property of Mohammad (PBUH). But Abu Bakr took it away from her despite protests by her and her husband Ali (PBUH) and their testimonies. I want to understand the Sunni perspective on this issue. Why didn’t Abu Bakr accept Fadak as belonging to Fatima (PBUH)? Did Abu Bakr based his ruling on Quran and the Prophet's Sunnah? If yes, what were the bases? Do Sunni scholars consider Abu Bakr's ruling on the issue as righteous?
