Can you summarize the main reasons for the split between the Sunnis and the Shiites?

Answer 1

the friends and followers of Ali believed that after the death of prophet, the caliphate and religious authority belonged to ALI. this belief came from consideration of Ali's position and station in relation to the prophet , his relation to the chosen among the companions , as well as his relation to muslim as general.

it was only the events that occurred during the few days of the prophet final illness that indicated that there was opposition to their view, contrary expectation, at the very moment when the prophet died and his body lay still unburied while his household and a few companion occupied with for his burial and funeral services , the friend and followers of Ali received news of the activity of another group who had gone to the mosque where community where gathered faced with this sudden loss of its leader.

this group ,Which was later ti form the majority , set forth in great haste to select a caliph for the muslim with the aims of the ensuring the welfare of the community and solving its immediate problems. they did this without consulting the household of the prophet , his relatives or many of his friends who were busy with funeral and without providing them with the least information. thus Ali and his companions were presented with a fait accompli .

Ali and his friends such as Abbas , Zubayr , Salman . Abu Dharr , Meghdad and Ammar, after finishing with the burial of the body of the prophet became aware of the proceedings by which the caliph had been selected . they proteted against the act of choosing the caliph by consultation or election , and also against those who were responsible for carrying it out.

they even presented their own proofs and arguments but the answer they received was that the welare of the muslims was at sake and the solution lay in what had been done.it was this protest and criticism which separated from the majority the minority that were following Ali and made his followers known to society as the partisans or shiah of Ali . the caliphate of the time was anxious to guard against this appellation being given to the Shiite minority and thus to have muslim society divided into sections comprised of a majority and a minority .

THE supporters of the caliph considered the caliphate to be a matter of the consensus of the community , and called those who objected the opponents of allegiance . they claimed that the shiiah stood, therefore opposed to muslim society .sometimes the shiiah were given other pejorative and degrading names.

shiism was condemn from the first moment because of the political situation of the time and thus it couild not accomplish anything through mere political protest.

Ali in order to safeguard the well-being of Islam and the muslims and also because of lack of sufficient political and military power did not endeavor to begin an uprising aganst the existing political order which would have been of a bloody nature . yet those who proteted against the established caliphate refused to surrender to the majority in certain questions of faith and continued to hold that the succession to the prophet and the religious authority belonged by right to Ali. they believed all spiritual and religious matters should be refered to him and invited people to becime his followers.
