I want to start learning about the inner meanings and tafsir of the quran. We have outer (dahir) and inner (batin) meanings of each verse. Do you know the name of his book that explains the inner meaning of Quranic verses? Can you please recommend a book or other books that do this.

The only ones who know the inner meanings of the Holy Quran are the Prophet and the Purified Progeny peace be upon them all. Tafseer Almeezan is a good combination of the apparant, and some of the hidden meanings based on narrations from the infallible ones and not the likings of a fallible individual.
