Abu Bakr accepted claims without witnesses but for Hazrat Fatima (sa) he objected

When Abu Bakr felt like it, he would accept a claim without the need for witnesses

As proof we have relied on the following esteemed Sunni works:

1. Sahih Bukhari, Volume 3, Book 48, Number 848: Book of Witnesses
2. Sahih Muslim, Volume 2 page 291
3. Sahih al Tirmidhi, vol 5 p 129
4. Sunan al Kabeera, Volume 6 page 302
5. Musnad Ahmad Hanbal, vol 3 p 307-308
6. Tabaqat Ibn Sa’ad, vol 2 part 2 p 88-89
7. Riyadh al Nadira, Volume 1 page 227
8. Tareekh ul Khulafa, page 69 Fadail fi Abu Bakr

We read in Sahih Bukhari:
Narrated Muhammad bin Ali:
Jabir bin Abdullah said, “When the Prophet died, Abu Bakr received some property from Al-Ala bin Al-Hadrami. Abu Bakr said to the people, “Whoever has a money claim on the Prophet, or was promised something by him, should come to us (so that we may pay him his right).” Jabir added, “I said (to Abu Bakr), Allah’s Apostle promised me that he would give me this much, and this much, and this much (spreading his hands three times).” Jabir added, “Abu Bakr counted for me and handed me five-hundred (gold pieces), and then five-hundred, and then five-hundred.”

Comment

All that it took was the word of Jabir that Rasulullah (s) owed him money; no witnesses were presented to corroborate his evidence. Abu Bakr’s opinion was that the money should be returned to Jabir, without the need for witnesses, he didn’t say anything that contradicted the Qur’an, yet when Sayyida Fatima (as) claimed that the land of Fadak was bequeathed to her as inheritance, he refused to grant her the land, on the premise that her words were questionable and the stipulated witnesses required to give evidence were not met.
If Jabir made a claim from the treasury, then by the same token Fadak also did not belong to Abu Bakr’s ancestors, rather it belonged to Sayyida Fatimah al Zahra (as), but the Khaleefa said that the land belonged to Muslims. If Jabir can receive monies from the Muslim treasury without the need of witnesses, then by the same token the Khaleefa could have also given Sayyida Fatima land from the Muslim treasury.
The narration informs us that Abu Bakr made the declaration at the time of the Hajj for people to come forward and make their claims in relation to whatever had been promised to them by Rasulullah (s). We ask those with brains, was Sayyida Fatima (as) a liar who presented false witnesses to substantiate her claim? Sayyida Fatima’s (as) testimony is false. The testimony of Imam Ali (as), and his two sons are also false, yet an ordinary companion’s claim without any witness corroboration is acceptable and he can attain property from the State treasury so as to prove the correctness of his claim.
