Munájátháy-i-Ṣíyám
From Bahaipedia
The Munájátháy-i-Ṣíyám, translated as Prayers for Fasting, are one of the Writings of Bahá’u’lláh.
Shoghi Effendi stated they was revealed in the latter period of Bahá’u’lláh's exile in Adrianople while He was resident in the house of Izzat Áqá and that their Revelation was in anticipation of the Kitáb-i-Aqdas.[1]
