He said that Ali is very careful in this matter (he is not inclined in encounter with the apostates) and if he did not attach any formal feature to apostates’ uprising nobody would go to war against them… In addition to describing the fear of Umar this statement also shows Ali’s moral status in Muslim society. That is such was his influence in the society that if he did not show any inclination in that war no one among the Muslims would go.
Therefore because of this fear Abu Bakr was too prudent in his behavior with Ali.” [2] “Indeed Umar had another fear and he did not want Hadhramaut to be an additional front for the new Caliphate.
Though Ali (a.s.) did not go to fight them, the regime of Caliphate even before seeking opinion of Ali (a.s.) was afraid of this matter and they sent Akrama.” [3] From this aspect it can be said: Caliphs also in every condition were not prone to give any government office to Ali and this was complimentary to ‘absence of inclination to always co-operate’.
In other words, Caliphs wanted an opportunity to strengthen pillars of their Caliphate and gain Ali’s indulgence into affairs, which to them was tantamount to legitimacy of their Caliphate. On the other hand whenever Ali co-operated he did so in a way, which could not be interpreted as his approval to their Caliphate. These and such efforts continued even after extending the borders of the country.

Pg. 102, Footnote 3 “The Caliph and his friends could not ignore the useful force such as him. They knew the courage and bravery of Ali. In lifetime of Prophet, they had witnessed from close Ali’s battles and fighting. So Ali with regard to battles was a very important element.
The Caliph and his associates also were not unaware of this or were opposed to it. On the other hand his absence from the wars and his isolation could be a matter of question in the society. Therefore the Caliph and his associates tried to involve Ali in government responsibilities. They wanted him to take part in military victories. This could have given credibility to their government.
