Some words used in tafseer are hard to understand for me. The explanation of the verses could have been deeper but I guess I am not at that level of understanding where the author is so no reflection on the Book. I am taking Quran classes while following Ahsaan Al Biyan and my experience of the classes is more effective in changing my life compared to reading Ahsan Al Biyan. But having said that it is a book of Allah and is superior in every way and it is my inability of comprehending the words that make the book less effective for me than the Quran classes. This is my version of the Book but others may find it more useful and meaningful according to their comprehension. Allah give us the desire to go through this Book with eagerness and desire for guidance. Ameen.
