This is from Al Ghazali's "People of Fiqh vs People of Hadith".
The hadith in question in one which says that the meat of animals with fangs is haram. It is interesting to note that the hadith that ibn Abbas is referring to is actually narrated by himself, ibn Abbas. So, it begs the question, how can Ibn Abbas reject a narration, per Ghazali, that he himself (ibn abbas) narrated as sahih). I kindly ask that you actually know what your talking about if you would reply. Thank you.
