This dude praising Hajaj now killed sahabah no wonder he supports this Darkie
Hajjaj killed Abdullah ibn Umar and Abdullah ibn zubayer and mus'ab ibn zubayer and the master of tabi'en said ibn jubayr and more.
Most scholars said about him that he was super ummayad supporter and he have a deep hate for prophet muhammed family.
And amir almuminin Umar ibn abdulaziz didn't used the name of hajjaj but use the title of the enemy of Allah when mentioning hajjaj.
The way hajjaj died was horrible worms start the come from his stomach to rest of his body, all this because said ibn jubayr asked Allah to be last person that hajjaj kills.
