Shaykh Rabī ibn Hādi Al-Madkhalī:
Nowadays an individual recites the Quran to another, however he does not know it’s meaning! He memorises the Quran, repeats it and he does not know it’s meaning. No understanding, and possibly he does understand, but he doesn’t act (by it).
The Quran requires understanding, implementation and action.
