Each interpreter is required to act methodically in his interpretation. Allameh Tabatabaii, who has interpreted the Quranic verses through discovering the intertextual relations among the verses, is not exempt from this rule. He has written al-Mizan commentary through Ijtihadi Quran to Quran method. In this study, we have dealt with the characteristics and features of his method of interpretation so that we can gain knowledge of Ijtihadi Quran to Quran method. There are two ways for knowing his 1. His speeches and writings; 2. Analysis of interpretation samples. By studying the writings of Allameh, we cannot find a remarkable solution in this area. The solution to this problem would be through analysis of interpretation samples, Allameh’s comprehensive approach to the Quran’s semantic system, methodical and Ijtihadi semantics, tradition - orientedness in interpretation method, use of Ghurar Al-ayat in interpretation of the words and verses of the Quran.
