To Mullá Husayn, more particularly, the Báb gave definite
injunctions to send Him a written report on the nature and progress of his
activities in Isfáhán, in Tihrán, and in Khurásán. He urged him to inform Him
of those who accepted and submitted to the Faith, as well as of those who
rejected and repudiated its truth. “Not until I receive your letter from
Khurásán,” He said, “shall I be ready to set out from this city on My
pilgrimage to Hijáz.”
(Chapter 6, ‘The Dawn-Breakers’)
