عمار بن ياسر
Noting an increase in anti-government tension around the Caliphate, Uthman's administration decided to determine its origins, extent, and aims. Some time around 654, Uthman called all twelve provincial governors to Medina to discuss the problem. During this Council of Governors, Uthman ordered that all resolutions of the council be adopted according to local circumstances. Later, in the Majlis al Shurah (council of ministers), it was suggested to Uthman that reliable agents be sent to various provinces to attempted to determine the source of the discontent. Uthman accordingly sent Muhammad ibn Maslamah to Kufa, Usama ibn Zayd to Basra, Ammar ibn Yasir to Egypt, and Abdullah ibn Umar to Syria. The agents sent to Kufa, Basra and Syria reported that all was well—the people were generally satisfied with the administration, although some individuals had minor personal grievances. Ammar ibn Yasir, the emissary to Egypt, however, did not return to Medina. Rebels there had been issuing propaganda in favour of making Ali caliph. Ammar ibn Yasir, who had been affiliated with Ali, abandoned Uthman for the Egyptian opposition. Abdullah ibn Saad, the governor of Egypt, reported about the opposition's activities instead. He wanted to take action against Ali's foster son, Muhammad ibn Abi Bakr, Muhammad bin Abi Hudhaifa, Uthman's adopted son, and Ammar ibn Yasir.
