I found something even more interesting here: "Abu Hanifa and al-Shafi'i and others worked with his(Abu Huraira's) Hadiths: When one forgets then eats while he is fasting, he must continue his fast. Although the Qiyas of abu Hanifa is that his fasting is ruined BUT he left his own Qiyas because of the narration of abu Huraiara. source: http://www.islamweb.net/newlibrary/showalam.php?ids=3 This directly contradicts both of the above and if one can bring us this from abu Hanifa's books then the matter is settled.
