Uthman, Third Righteous Caliph, is killed by rebels
The Third Righteous Caliph, Uthman, was killed at the end of a Siege.
When the rebels besieged the house of Uthman, the siege was not severe at the early stage. The rebels merely hovered around the house of Uthman, and did not place any restrictions on the movements of Uthman. Uthman went to the Prophet's Mosque as usual, and led the prayers. The rebels prayed under the leadership of Uthman.
