In Baghdád, in answer to the questions of an uncle of the Báb, Bahá'u'lláh revealed in the span of two days and two nights the Kitáb-i-Íqán — the Book of Certitude — a work of such sweep and majesty that it unveils the meaning of all the Scriptures of the past and stands among the greatest doctrinal works of His entire Revelation. Adib Taherzadeh recounts the awe of its outpouring.
