The Hanaabilah were Ignorant and or stubborn?

In the explanation of a famous book on the beliefs of the Maaturidiyah, The author of the text is,

Najm Ad-Deen An-Nasafi (461-537 Hijri), and the author of the explanation is, Sa'ad Al-Deen At-Taftazaani (712-793 Hijri)

The Author of the text said:

(The Qur'an is the speech of Allah The Most High, not created) 

The Author of the explanation goes on to say:

"What follows the Qur'an  is the speech of Allah, as the scholars have mentioned concerning it saying, The Qur'an is the speech of Allah The Most High, not created. However it is NOT said the Qur'an (Itself) is not created, so that by doing so one would come upon the (Incorrect) understanding that it was composed of sounds and letters that always existed. This is how the Hanaabilah have understood it out of Ignorance  or Stubbornness."

This is not to say I agree with the above information, in fact I don't. However it's posted to show that the Hanaabilah have always been accused of something wrong.
