Mukhtar al-Thaqafi
During the rule of Mukhtar al-Thaqafi, who had seized Kufa in October 685, Shimr was among the agitators who attempted to topple Mukhtar. After the rebellion was defeated, Shimr escaped to Sadama, a place between Kufa and Basra. Mus'ab ibn al-Zubayr ruled Basra at the time and Shimr wrote him a letter requesting assistance. The letter was intercepted by Mukhtar's soldiers led by Abu Amra Kaysan. With his location thus exposed, Shimr was found by Kian alfarisii killed. Other variants suggest that he was wounded and sent to Mukhtar, who then killed him.
