Bahá’u’lláh invests ‘Abdu’l-Bahá with the right of interpreting His holy Writ (see also note 145).
185. the School of Transcendent Oneness [#175]
In this verse and the ones which immediately follow it, Bahá’u’lláh confronts one of the reasons some of the Bábís rejected His claim to be the Promised One of the Bayán. Their rejection was based on a Tablet addressed by the Báb to "Him Who will be made manifest" on the reverse side of which the Báb had written: "May the glances of Him Whom God shall make manifest illumine this letter at the primary school." This Tablet is published in Selections from the Writings of the Báb.
These Bábís maintained that, since Bahá’u’lláh was two years older than the Báb, it was not possible for Him to receive this Tablet "at the primary school".
Bahá’u’lláh here explains that the reference is to events transpiring in the spiritual worlds beyond this plane of existence.
186. We accepted the verses of God ... which He presented unto Us [#175]
In His Tablet addressed to "Him Who will be made manifest", the Báb characterizes the Bayán as an offering from Him to Bahá’u’lláh. See Selections from the Writings of the Báb.
