The Necessity of the Quran Exegesis through the Quran; Essential or Option

The Quran exegesis through the holy Quran is of the exegetic methods in the present day which it has been paid attention. Allameh Tabataba’i is counted of precursors of this method. There is a question here if the essence of some verses of the noble Quran in the revelation time is that the verses have not been understood except by referring to some other verses and the Quran addressees were not able to perceive God’s intent except by referring to the other verse. The investigation in this paper shows that there are no verses in the nobleQuran that their intents had not be clear for the Quran addresses at the time of descending (nuzūl al-Qurʾān). They did not need to refer to the other verses in order to understand the intent of the Quran. But because of the passage of time and being neglected the evidences of the intention, ambiguity emerged in some verses of the holy Quran. One of the evidences which helps to understand the intentions of the verses is the verses with one theme that they are scattered over the noble Quran. Therefore, the need of the Quran exegesis through the holy Quran is option and not essential.
