Abd al-Malik ibn Marwan was one of the Muslims who used to get upset if someone killed an ant ascending to power but after taking power he spent his life killing Muslims. Like Abd al-Malik ibn Marwan, Ubaydullah ibn Ziyad had the Shias of Ali (as) and other Muslim leaders captured and put to death. He is renowned for the fact that before killing them he use to inflict them with torturous wound like cutting their arm and legs on opposite sides and putting hot iron into their eyes.
