Uthman approved seeking to please all.
Kufa remained a source of instigations albeit from a minority. In 656 when the Egyptian instigators, in co-operation with those in Kufa, marched onto the Caliph Uthman in Medina, Abu Musa counselled the instigators to no avail.
Caliph Ali's era (656�661)
Capital of Fourth Caliph Ali (656)
Upon Uthman's murder by the Kufan instigators, governor Abu Musa attempted to restore a non-violent atmosphere in Kufa. The Muslims in Medina and elsewhere supported the right of Ali ibn Abu Talib to the caliphate. In order to manage the Military frontiers more efficiently, Ali shifted the capital from Medina to Kufa.
The people of Syria and their Governor, Muawiyah, who was in search to seize the initiative himself used the confusion caused by the assassination of Caliph Uthman and being disturbed by the brutal assassination of the Caliph Uthman at the hands of the few Kufan and Egyptian instigators, demanded retribution. Ali did not disagree except at the timing of the retribution as those instigators held tremendous power and had allinged themselves within the Ali's army in his region after the assassination of the Caliph. In an emotionally charged atmosphere, misunderstandings developed between Ali's camp and that of the Syrians and Muawiyah's refusal to give allegiance to Ali as the Caliph without Ali avenging Uthman first eventually, led to war.
Eventually, Ali was killed in the mihrab of the great mosque of Kufa by Ibn Muljim; a traitor to Ali who was convinced to murder him by a beautiful woman whom he wanted to marry. To commit her condition, Ibn Muljim was told to murder Ali while praying, where Ali was hit by a poisonous sword while he was prostrating.
Muawiyah's era (661�680)
