Domain of Authenticity of Exegetical Hadiths

The main points of the present paper are as follows: 1. every exegetical statement requires conclusive evidence or reliable evidence based on irrefutable one; 2. hadiths possessing common-sense evidence and rationally reliable hadiths which are utilized as evidence both practically and exegetically; 3. unreliable hadiths are used as evidence only for practical aspects of the Holy Quran's verses; 4. although both groups of hadiths should be accepted as reliable by religious law but the secret of this classification is found on three points: a) defining tafsir and its real nature, b) existence of indication for real evidence in rationally reliable hadiths, c) lack of the criteria for such an indication in obligatory developed hadith; 6. classification of statements into scientific and practical is not acceptable regarding the authenticity of rational hadiths but reliability of their issuance is subject to their importance and significance; 7. studying the advantages of unreliable exegetical hadiths; 8. incompatibility of exegetical haiths with the holy Quran and sunna.
