The love of the nightingale for the rose is a common theme in Persian literature, particularly in mystic poetry, where the nightingale's yearning is used as a metaphor for the soul's yearning for God. (The Rose and nightingale in Persian literature. （原始内容存档于2008-01-22）.) One night during his stay in the Garden of Ridván, Bahá'u'lláh is recorded as having spoken the following words: "Consider these nightingales. So great is their love for these roses, that sleepless from dusk till dawn, they warble their melodies and commune with burning passion with the object of their adoration. How then can those who claim to be afire with the rose-like beauty of the Beloved choose to sleep?" (Taherzadeh, Adib. The Revelation of Bahá'u'lláh, Volume 1. Oxford, UK: George Ronald. 1976: 259 [2017-06-22]. ISBN 0-85398-270-8. （原始内容存档于2018-08-24）.)
