Ibn Katheer says in Al-Bidayah...
Ibn Katheer says in Al-Bidayah: (When the people of Al-Medina returned from Yazeed, Abdullah bin Mutee'a and his companions walked to Muhammad bin Al-Hanafiyah. They wanted Muhammad to agree to dismiss Yazeed, but Muhammad refused. Ibn Mutee'a said: "Yazeed drinks alcohol, does not pray, and ignores the rule of the Book." Muhammad answered them: "I never saw what you are saying about him.
I came to him, and stayed with him for a while and I saw him taking care of his prayers, looking for goodness, asking about jurisprudence, and clinging to the Sunnah.[Al-Bidayah wa Al-Nihayah for IbnKatheer,vol.8,p.236] It is agreed by Sunni and Shi'a alike that Yazeed was an ill character individual, and he is reviled throughout the world in Muslim circles. Curiously Abu Sulaiman seems to depart from the common Sunni line and all of a sudden endorses the piety of Yazeed!
No true Sunni would ever utter praise for Yazeed. It is extremely insulting to see that yet again Abu Sulaiman is presenting his Nasibi thinking and cloaking it as Sunni Islam. In any case Abu Sulaiman has failed to substantiate his claim. Assuming that this statement attributed to Ibn al-Hanafiyya is not a fabrication, Muhammad bin Hanafiyya is stating that he (personally) had NOT seen Yazeed drinking this so could not verify the allegation.
Had Abu Sulaiman had an ounce of honesty in him, this was a fact that few ulama of Ahlul Sunnah deny. Ibn Kathir's comments on Yazeed the drunkard Interesting the very same text al Bidaya from where Abu Sulaiman had sought to extol the virtues of his Imam Yazeed, also contains these comments of Ibn Kathir proving that he was indeed a drunkard.
Ibn Kathir writes in al Bidayah Volume 8 page 239: "Traditions inform us that Yazeed loved worldly vices, would drink, listen to music, kept the company of boys with no facial hair, played drums, kept dogs, not a day would go by when he was not in a drunken state".
Ibn Atheer's comments on Yazeed 'the drunkard' In Tareekh al Kamil Volume 3 page 450 Ibn Atheer narrates from Munzir bin Zabeer: "Verily Yazeed rewarded me with 100,000 dirhams but this cannot stop me from highlighting his state, By Allah he is a drunkard" Allamah Dhahabi's naration and verdict on Yazeed 'the drunkard' Yazeed's drinking despite Abu Sulaiman's denials is such an established fact that even Dhahabi, relied on as an authority by Abu Sulaiman, testifies to this fact.
