[^3] The extent of their political differences...
[^3] The extent of their political differences, which had religious roots from the very beginning, increased with time. For instance, some of the from the very early days did not recognize a role for the Prophet's Sunnah by the side of the Qur'an. This belief was the important characteristic of the Qurayshi faction.
Denial of the religious authority of the Prophet's prescriptions and prohibition on the writing and narration of hadith are clearly visible elements in the stance of the leaders of this faction right from the Prophet's days.
Without doubt one can say that the of the Prophet (s) formed two different groups from this angle: those who believed in the necessity of following the Prophet (s) in all aspects and those who did not consider it obligatory to follow the Prophet (s) in matters relating to government and political affairs. The pre-Islamic influence of the Quraysh, along with other factors, led the latter group to acquire power.
A little later when Abd al-Rahman ibn Awf laid down the condition that he would deliver the office of the caliphate to the candidate who would follow the practice (sirah) of the Shaykhayn (i.e. Abu Bakr and 'Umar) and Imam Ali insisted that he would base his policy only on the Qur'an, the sirah of the Prophet and his own judgements (ijtihad) it was obvious that the religious difference was gradually expanding.
Until the time when Umar was in the office of the caliphate, the generality of people, excepting the followers of Imam Ali, followed the decrees (fatwa) of the State, not attaching much significance to the difference that existed at that time between the practice of the Prophet (s) and that of others.
But when Uthman, besides allegations of political and financial misdemeanor, was accused of acts that were considered to be religiously deviant (bid'ah) and he was challenged by a large number of , the problem arose as to whom the people should regard as a competent religious authority. In other words, whom were they to emulate?
If we note that it were the opponents of the Qurayshi faction who led the movement against Uthman, we can understand better the connection between differences on political and religious issues. 'Uthman was killed at the end of 35 H./656 and Ali assumed the duties of caliphate. Now the leader of the anti-Qurayshi faction, who incidentally had no role in the revolt against Uthman and whose counsel went unheeded by the extremists, had assumed the office of the caliphate.
