The Thematic Domain of the Quran according to the Quran

One of the issues worthy of research in the field of the holy Quran is the domain of its utterances termed as the thematic domain of the holy Quran. To reveal the domain of the holy Quran, we can, or rather we must refer to the verses of the Quran. Extra textual methods are not sufficient here. Since this book is a miracle, its utterance in this regard is authoritative. The present article deals with the verses which directly testify to or indicate the thematic domain of the Quran. The context of these verses and the hadiths interpreting them is indicative of the guidance role of the Quran for the holy prophet and his Household (p.b.u.t) On the one hand, these verses state that the revealed verses do explain everything. On the other hand, according to evidence and arguments, the holy Quran has an internal meaning, in addition to its external one, which is not available to anybody but the holy prophet and his successors (Ahl al-Bayt). So the thematic domain of the Quran is peculiar to them and includes the internal as well as external meanings of the Quran.
