Shiavault - a Vault of Shia Islamic Books Hisham ibn Hakam The Debate of Hisham with the chief of the Kharajites (Khawarej) Hisham, who was never defeated in debates, was a universal champion and his fame spread every where. He was always victorious over his opponents in every debate. Every one was anxious to witness his debates.
Haroon, the most powerful caliph of the time, who was to a certain extent among the opponents, was also more anxious than others to watch the discussion and the speech of Hisham. So one day, he ordered Yahya ibn Khaled, his minister to arrange a meeting and put Hisham face to face with Abdullah ibn Yazid Abazi,[^1] the chief of the Kharajites,[^2] who was also one of the famous learned men of the time.
The caliph also sat in a secret place behind the curtain in such a manner that he was able to listen to their discussions clearly but they could not see him. Then the caliph ordered Yahya ibn Khaled Barmaki to ask Abdullah to put forth his questions to Hisham.
Yahya, by the order of Haroon, turned his face to Abdullah and said: "Put forth your questions to Aba Muhammad, Hisham." Hisham (by taking this opportunity) said: "The Khawarej have no right to ask us about anything." Abdullah -Why is this so? Hisham - Because you were the people who first believed as we did in the justice of the man (i.e. Amirul Mu'mineen Ali (a), his Imamate and virtue, and then separated yourself from us and initiated intrigues and enmity with him.
As we still have the same belief, so your first faith and agreement is a proof for us; your later opposition and enmity does not harm us and your arrogation is not accepted as an injury to us. This is so because the contradiction made after acceptance is not effective, your witnessing as an enemy of mine is acceptable if it is useful to me as your enemy. But if it is harmful to me as your enemy it is unacceptable.
Yahya ibn Khaled - O Hisham, you have almost defeated Abdullah and have brought him to the verge of defeat at the edge of a cliff. However, treat him moderately, as the caliph wants you to continue the discussion with him (although he did not hint at all that the caliph was present behind the curtain). Hisham - I am ready for debate, but there is a difficult point.
