What follows is my provisional translation (in other words, not official or authorized; see here for more) of a passage from the Kitáb-i-Badí‘ of Bahá’u’lláh, which appears on p. 62 of Bahá’í-Verlag’s printing of that book, published in 2008.
No contradiction hath ever entered, nor will it ever enter, the hallowed realm of the holy Manifestations of God. Such contradictions lie in the very essence of the people, not in the Revelation of God.
A typescript of the original Persian text of the passage appears below (all punctuation and vowel marks mine).
