Let me try to make this short because my computer continues to cut off!
The issues of disputes were promised to happen and predicted by Prophet Muhammad(peace and blessings be upon him). It does not matter about Abdullah Bin Saba but he did existed during that time period and he did had something to do with the rebellion against Khalif Uthman(radiallahu anhu). Yes, some Egyptians were included in the rebellion including other companions and Ayesha(radiallahu anha). But all this was predicted anyway. Khalif Uthman was right about his decisions and also to let you know that ALI himself had his two sons (Hasan and Hussein) guard the place of Uthman! So what does this tell you? It should tell you that Uthman and Ali were close allies and friends!
As for the Hadiths. The Qur'an itself is a collection of Authentic Hadiths. Back then before the Qur'an was in a Book form the hadiths and the Qur'an were followed by the early Muslims by heart and memorization. Read something about Hadiths:

The Hadith Qudsi are Authentic Hadiths but were not included in the Qur'an because it was not recited with Prophet Muhammad before he died when Angel Gabriel(peace be upon him) recited it with him twice. The reviewing recitation became the Qur'an.

What is needed now is reform in the Muslim world! Through this reform spiritually and intellectually the Muslims would eliminate the division and usher in a new era of responsible industrial production and space exploration.
This is my position.
