He was such that he openly denied the messenger ship of the Messenger (P.B.U.H&H.P). He made his beliefs clear in the following couplets:
“Banu Hashim (the Prophet and his family) has played a game to obtain temporal power.
The fact is that neither an angel came to them nor any revelation descended.”
Intoxicated in this wrong belief, he considers that the tussle between Islam and disbelief to be a battle between two clans and is overjoyed that he has succeeded in taking revenge from the progeny of the Prophet on behalf of his ancestors.
“If only my ancestors who died in Badr had been alive and seen how their opponents (Ahl al-Bayt of Prophet) were suppressed, they would have screamed in joy: O Yazid! May your hands never tire! We have killed their leader and in this way took revenge of Badr. And I won’t be eligible to be called the descendant of the fighters of the Ditch (Khandaq) if I had failed to take revenge from Muhammad and his relatives.”
