Shiavault - a Vault of Shia Islamic Books A Shi'ite Encyclopedia (chapter 10) Abdullah Ibn Saba (part Iii) Agitation Against Uthman Sayf alleged that the main reason behind the agitation against Uthman was Abdullah Ibn Saba. He provoked Muslims of different towns and provinces such as Basra, Kufa, Syria, and Egypt, to rush to Medina and to kill Uthman since he believed Uthman had occupied the seat of Ali.
Sayf also alleged that the companions inside Medina such as Talha and Zubair did not oppose Uthman. Similar to his other allegations, this allegation of Sayf Ibn Umar about Abdullah Ibn Saba has NOT been reported by any other reporters. No trace of Ibn Saba can be found on the issue of agitation against Uthman, except through Sayf. In fact, other authorities have a totally the opposite story.
Should a reader of Islamic history be liberated from his emotion toward or against the third Caliph, he can be assured that the call for a revolt against Uthman did not start in Basra, Kufa, Syria, or Egypt. The weakness of Uthman in handing the affairs of the State caused many companions to oppose him. This naturally resulted in a power struggle among the influential companions in Medina.
Sunni historians such as al-Tabari, Ibn Athir, and al-Baladhuri and many others provide traditions (reported by other than Sayf) which confirm that the agitation against the Caliph started right inside Medina by some influential individuals among the companions. These companions were the first who asked the other companions, resided in other cities, to join them in revolt against Uthman.
Ibn Jarir al-Tabari reported: When the people saw what Uthman was doing, the companions of the Prophet in Medina wrote to other companions who were scattered throughout the frontier provinces: "You have gone forth but to struggle in the path of Almighty God, for the sake of Muhammad's religion. In your absence the religion of Muhammad has been corrupted and forsaken. So come back to reestablish Muhammad's religion." Thus, they came from every direction until they killed the Caliph (Uthman).
