Comparative study of Feyz-e Kashani and Ibn Kathir's interpretive method

The interpretation of Al-Quran Al-Azim by Ibn Kathir is one of the narrative interpretations of the 8th century which is influenced by Tabari's Jame-Albayan interpretations and also interpretive principles of Ibn Timie. Grounds for forming this interpretation and bases of this interpretation on the one hand, and on the other hand interpretive methods of the exegetist have given superior features to this interpretation and made it uitable to research; especially when we compare it with interpretations such as those by Safi Feyze Kashanis, which is on the basis of Hadith based approach by Shiite scholars in eleventh and twelfth centuries followed by interpretation development in these two centuries. The question which is raised in here is that: Which interpretive method have Feyz-e Kashani and Ibn Kathir followed in their own interpretations ? To respond the question we should say that the interpretive method of Ibn Kasthir is Quran to Quran and Quran to custom on the basis of sunna narrative sources and Feyz-e Kashanis, method is combined whit inferior paraphrases based on Shiites, narrative sources.
