Re: Correct me
My own understanding is as mentioned by Curious One i.e. the fight for successor of Prophet. Companions vs Ahle-bait. Followers of both went to extremes in times of Muwayiah and the divide increased multifolds including badmouthing of opposite leaders during Friday sermons etc. All this "hate" resulted in totally discarding source of info from other side which gave rise to differences in aqaaid.
If you can rise above the level to discard the old-ingrained-differences and read you'll find the common land from there you can actually laugh (sadly) at people who are fighting at the differences.
very sensible post captain1
but may I add one thing the argument between the early companions for the leadership was not as simple as " ahlulbayt vs companions"
and it is extremely wrong to assume that the faction of muawiyah represented the original companions amongst the muhajirin and ansar, I can safely say this without prejudice.Umar(ra) himself had established a system in which the early companions esp. those who were veterans of the Ghazwas were given priority in all respects
and the caliphate was strictly off-limits to "freed ones" like muawiyah.
