In the Baha'i Faith

The nightingale is used symbolically in the Baha'i Faith to represent the founder Baha'u'llah. Baha'is utilise this metaphor to convey how Baha'u'llah's writings are of beautiful quality, much like how the nightingale's singing is revered for its beautiful quality in Persian music and literature.

Nightingales are mentioned in much of Baha'u'llah's works, including the Tablet of Ahmad, The Seven Valleys, The Hidden Words, and the untranslated Tablet of the Nightingale and the Owl.
