the way of the Quran and the Sunnah of Muhammad, and second, he should follow the example of Abu Bakr and Umar. Ali is said to have accepted the first condition but declined the second one, adding that he would rely only on his own judgment in the absence of any precedent from the Quran or the Sunnah. Abd al-Rahman then presented the same conditions to Uthman who readily accepted them. It has been suggested that Abd al-Rahman was well aware of Ali's disagreements with the past two caliphs and that Ali, known for his sincerity, would have inevitably rejected the second condition. Uthman's reign was marked with widespread accusations of nepotism. Under Uthman's rule, his tribe, the Banu Umayyad, is said to have regained its pre-Islamic influence and power. Uthman installed his relatives, including his cousin, Muawiya, to rule the Islamic territories. According to Glassé, Uthman was assassinated by rebels in 656, in a climate of growing dissension against the despotism of the Banu Umayyad. Shortly after the assassination of Uthman, the caliphate was offered to Ali, who declined the position at first. Aslan attributes Ali's initial refusal to the polarizing impact of Uthman's murder on the community, while Durant writes that, "[Ali] shrank from drama in which religion had been displaced by politics, and devotion by intrigue." In the absence of any serious opposition and urged particularly by the Ansar and the Iraqi delegations, Ali eventually accepted the first pledges of allegiance in the Prophet's Mosque in Medina. It appears that Ali personally did not force anyone for a pledge though the strong pro-Ali atmosphere of Medina might have exerted some pressure on his opponents. In particular, Sa'ad ibn Abi Waqqas, Abdullah ibn Umar and Usama ibn Zayd refused to acknowledge the authority of Ali. Talha and Zubayr, both companions of Muhammad with ambitions for the high office, likely gave their pledges though they later broke their oaths, claiming that they had pledged their allegiance to Ali under public pressure. There is, however, less evidence for violence here than in Abu Bakr's election, according to Madelung. Ali inherited the internal problems of Uthman's reign. Immediately after his election, Ali quelled an armed insurrection led by Aisha, a widow of Muhammad, and Talhah and Zubayr. Afterwards, Uthman's governor of Syria, Muawiya, declared war on Ali and a long and indecisive civil war ensued. The first four caliphs are referred
