sunnis always say that there were very good relations between abu bakar and mola ali; and every thing was good in that era etc etc

let us see if it is so

sunni scholar of jamia tul azhar, allama mohammad abdah says in his book sharah nahj ul balagha

talha was inclined towards uthman, and is this reason not sufficient that he rejected ali because he was tamemi, and there were clashes between bani hashim and bani tamem due to abu bakar becoming caliph

[nahj ul balagha, sharah mohammad abdah, vol 1, page 33]
