Mirza Áqá Ján [Bahá’u’ll’áh’s amanuensis] related to Nabil that, one day in Kázimayn, when both he and Aqá Muhammad-Hasan-i-Isfahání [a merchant] were in the presence of Bahá’u’lláh, in the house of Hájí ‘Abdu'l-Majid-i-Shirázi, He asked the host whether he wished to hear the Badí’ (Unique) language, which, He said, was the language used by the denizens of one of the worlds of God. He then proceeded to chant in that language. Mirzá Áqá Ján said that hearing this language had a wonderful effect on the listener.
One day, Mirzá Áqá Ján related, Bahá'u'lláh said to Haji ‘Abdu’l-Majid: ‘Haji, you have heard the Badí’ language, and witnessed God's supremacy over His worlds. Render thanks for this bounty and appreciate its worth.’” "
