Many companions of Imam Ali [a] supported Imam Husayn [a]. Many Muslims supported him, too.
Ubaidullah bin Ziyad arrived in Kufa, He began arresting and imprisoning Imam Husayn's supporters.
Maytham, Mukhtar al-Thaqafy, Abdullah bin al-Harith were in the same prison.
Imam Husayn [a] died a martyr for Islam. The prisoners felt pain for him.
Mukhtar said to his two friends:
Be ready to meet Allah! After Imam Husayn's killing, Ubaidullah bin Ziyad will kill the Imam's supporters!
Abdullah bin al-Harith said:
Yes, he will kill us sooner or later!
No, he won't kill you. My dear Imam Ali [a] has told me that you (Mukhtar) will get revenge of Imam Husayn's killers. And you will kick Ubaidullah's head with your foot.
Then Maytham said to Abdullah bin al-Harith:
You'll rule Basrah.
