A companion Nayyar b Ayyad Aslami who joined the rebels exhorted them to enter the house and assassinate Uthman. When the rebels under the leadership of Nayyar b Ayyad advanced to rush into the house, Kathir b Salat Kundi a supporter of Uthman shot an arrow which killed Nayyar. That infuriated the rebels. They demanded that Kathir b Salat Kundi the man who had killed Nayyar should be handed over to them. Uthman said that he could not thus betray a person who had shot an arrow in his defense. That precipitated the matters. Uthman had the gates of the house shut. The gate was guarded by Hasan, Hussain, Abdullah b Zubair, Marwan and a few other persons. Open fighting now began between the rebels and the supporters of Uthman. There were some casualties among the rebels. Among the supporters of Uthman Hasan, Marwan and some other persons were wounded.
