Faulty formulation: The Qur'an's only claim upon the believer is accurate and beautiful recitation; understanding and acting on it are unrelated.
Correct formulation: Its rights include recitation, sound understanding and action in accordance with its guidance. Proper pronunciation and beautiful recitation are valuable, but they cannot substitute for knowledge and obedience.
Application: Someone recites a divine command beautifully but ignores its meaning and practical demand. One aspect of engagement with the Qur'an has been fulfilled, not every duty owed to it.
