Mu’Tazila Criterion Of Hadith
I am not aware of the specifics of these objections but usually these are same objections raised by traditional ulema such as: 1. It leads to hadith rejection based on aql/rationalism 2. Quran tafsir based on aql/rationalism 3. Generally speaking that the mutazila were deviated sect and we should stay from their ideologies and methods as it will eventually lead one to become ahl quran etc.
