Mus'ab bin al-Zubair

Abdullah bin al-Zubair thought about a new, strict ruler to appoint over Basrah. He chose his brother Mus'ab to carry out the task. Mus'ab bin al-Zubair arrived in Basrah and addressed its people:

Some people have told me that you surname your rulers. Before you surname me, I have surnamed myself al-Jazzar (butcher).

Some persons killed innocent people. They escaped from Mukhtar's justice. They began urging Mus'ab to fight Mukhtar.
