January 14

Each day the guards would descend the three steep flights of stairs of the pit [Siyah-Chal], seize one or more of the prisoners, and drag them out to be executed. In the streets of Teheran, Western observers were appalled by scenes of Bábí victims blown from cannon mouths, hacked to death by axes and swords, and led to their deaths with burning candles inserted into open wounds in their bodies. It was in these circumstances, and faced with the prospect of His own imminent death, that Bahá’u’lláh received the first intimation of His mission:

“One night, in a dream, these exalted words were heard on every side: ‘Verily, We shall render Thee victorious by Thyself and by Thy Pen. Grieve Thou not for that which hath befallen Thee, neither be Thou afraid, for Thou art in safety. Erelong will God raise up the treasures of the earth—men who will aid Thee through Thyself and through Thy name, wherewith God hath revived the hearts of such as have recognized Him.’”
