To answer such deviation in analysis of historical events we first dwell upon some historical proofs that clearly disprove the deviated analysis: Imam Ali (a.s.) absolutely and always refrained from accepting a government post in Caliphs’ rule; more than this, Caliphs also were well aware of such attitude of the Imam towards them.
Regarding his cooperation with the First Caliph, it can be said: Documentary Proof A) When some persons like Aswad Ansi, Musailama and Sajjah claimed prophethood and Abu Bakr prepared an army to fight them, he consulted Amr bin Aas regarding the command of forces and asked for his opinion about the choice of Ali. Amr bin Aas told him: Ali would not cooperate with you; [2] so Abu Bakr gave up the idea.
[3] Documentary Proof B) In the same way the Caliph tried to appoint His Eminence (a.s.) for quelling disturbances of Kinda tribe, but Umar considered it impractical. [4] The only instance when it could be claimed that Abu Bakr assigned command to Ali (a.s.) was the responsibility of guarding the original road to Medina in a time when he (Abu Bakr) himself had caused the army of apostates to attack the city and they had reached near Medina.
Here the point worth nothing thing is that this case is also narrated only in Sunni sources and there are many doubts in its authenticity**[5]** an example of [1] Muhammad Barfi: Seemai Ali Az Manzar Ahle Sunnat (Portrait of Ali from the Sunni point of view), [1 st Edition 1380], Pg. 104 [2] The later history shows that the reason why Caliph referred to Amr Aas was that the latter had a deep understanding of the personality of Amirul Momineen (a.s.).
The Qasida of Ghadeeriya also mentions this point. [3] Yaqoobi: Tarikh Yaqoobi, Vol. 2, Pg. 129 [4] Allamah Ja’far Murtuza Amili: Tahlili Az Zindagi-e-Siyasi Imam Hasan Mujtaba (a.s.) (1 st Edition), Pg. 198; quoting from Futuh Ibne Athim, Vol. 1, Pg. 72 [5] Refer: Ali Labbaf: A Victim Lost in Saqifah, Vol. 3, Pgs.
143-144 which is as follows: “Ibne Athir, in the portion of his history dealing with the campaign of First Caliph against false prophets, mentions: Abu Bakr assigned Ali, Zubair, Abdullah bin Masood and Talha to guard the hilly roads around Medina.
