146 In The Bayan It Had Been Forbidden You To Ask Us Questions #126
The Bab forbade His followers to ask questions of Him Whom God will make
manifest (Baha'u'llah), unless their questions were submitted in writing
and pertained to subjects worthy of His lofty station. See Selections from
the Writings of the Bab.
Baha'u'llah removes this prohibition of the Bab. He invites the believers
to ask such questions as they need to ask, and He cautions them to
refrain from posing idle questions of the kind which preoccupied the
men of former times.
