Most Mullahs, Haffaz (memorizers), and even Arabs do not understand the Qur'an.
I can give you hundreds of words and ayahs from the Qur'an. Go to any Arab and he won't be able to tell you their true meanings. Sounds weird but try it and you will find it true.
Why? Muslims have frozen the Qur'anic lexicon for a thousand years neglecting the fact that all languages undergo evolution with time. Today's Arabic will not let you understand the Qur'an correctly. Study the first tafsir, "Imam" Tabari, and you will only know what he understood in the 10th century CE language.
Do you know that the ancient 'super Imams' had Forbidden Qur'an translation in any language? The 'crime' was punishable by beheading in public. The first-ever English translations by Muslims were done in the 1930s!
Let me give you a simpler example. Read the first-ever Urdu poet WALI MUHAMMAD DAKKANI (1667-1707) and see how much of him you understand; hardly 10%.
