God’s glorious handiwork

To “discern with the eye of oneness His [God’s] glorious handiwork, and look into all things with a searching eye.” - Baha'u'llah (‘Tablets of Baha'u'llah revealed after the Kitab-i-Aqdas’)

Question: Considering the history of the Faith, can you cite an incident which clearly demonstrated Baha’u’llah’s intimate knowledge of the Qur’an and His respect for it, before He became a Manifestation of God?
