Once the uncle of the Báb (Hájí Mírzá Siyyid ‘Alí) discussed the claim of the Báb, with his younger brother Hájí Mírzá Hasan-‘Alí. During this discussion, the younger brother accused his older brother of having departed from their ancestral religion and chosen to follow their nephew. Hájí Mírzá Siyyid ‘Alí (the older brother) then responded:

You should know well that God Most High has fulfilled the proof before me. After what I saw with my own eyes in His childhood and what I know with complete confidence about him since His adulthood, there is no room for doubt for anyone, especially for me. Have you forgotten our journey to Sabz-Púshán when He was a child aged nine years old? There was a group of us, and He came along as well. When we arrived, being completely exhausted, we performed our ablutions, offered our late afternoon and the evening obligatory prayers, paid our homage of visitation, ate dinner, and went to bed.

It was not long after, at midnight, that I awoke and noticed that He was not in bed. Deeply perturbed, I was overtaken with anxiety that perhaps He had fallen from the mountain. Finally, after searching extensively, I heard a voice raised in the obligatory prayer and prayers of glorification to the Lord, coming from the lower extremities [of the mountain]. When I followed the melody of that chant, I found the Child, standing alone and in private, in consummate rapture voicing prayers and supplications to the One Who transcends all mention, on the deserted mountainside and at that late hour of the night.

My beloved brother, I ask: After observing such things, is there any room for doubt? With a knowledge born of certainty, with truth that stands most manifest, and with my own unimpeachable observations, it is thoroughly evident that the Promised One whom we had anticipated has now appeared after twelve hundred and sixty years.
