"... The title 'Hidden Words' was given by Bahá'u'lláh because there is a tradition in Islam, that Fatimih, Muhammad's daughter, grieved greatly over the Martyrdom of her son, and God sent Gabriel to speak encouraging words to her. These words were 'hidden', only she having heard them, and in these latter days the Promised One has revealed them, thus fulfilling a tradition." (From a letter written on behalf of Shoghi Effendi to an individual believer, December 20, 1949)
"With regard to your question concerning the meaning of the name 'Hidden Words'. It is, indeed, one of the most suggestive titles of the Writings of Bahá'u'lláh. These words are called hidden due to the fact that men have had neither the knowledge nor a true sense of appreciation of them before they were revealed by Bahá'u'lláh. It is through Him, Who is the sole Mouthpiece of God in this age, that spiritual realities and truths have been once more reinterpreted and revealed afresh to mankind. Bahá'u'lláh's Message is thus the only key to a true revealed afresh to mankind. Bahá'u'lláh's Message is thus the only key to a true understanding of the mysteries that envelop man's spiritual life." (From a letter written on behalf of Shoghi Effendi to an individual believer, September 1, 1935)
