According to Imam Khomeini, the major element in the Exegesis (Tafsir) of the Holy Quran is expressing the purposes of the verses of the Holy Quran and stating the intention of Allah the Almighty.
He believed that no thorough and exhaustive interpretation of the Holy Quran is provided yet and expresses his dismay why brutal monarchs during the early period of Islamic history did not allowed the Twelve Infallible Imams to provide a perfect interpretation of the Holy Quran.
He does not consider available interpretations as perfect interpretations and only considers them as exemplifications and definitions, because he refers to interpretation as disclosing the intention and purposes of the verses of the Holy Quran.
