September 7

After this event [martyrdom of the Báb] there was wrought by a certain Bábí a great error and a grave presumption and crime, which has blackened the page of the history of this sect and given it an ill name throughout the civilized world. Of this event the marrow is this, that during the time when the Báb was residing in Ádhirbayján a youth, Sádiq by name, became affected with the utmost devotion to the Báb, night and day was busy in serving Him, and became bereft of thought and reason. Now when that which befell the Báb in Tabríz took place, this servant, actuated by his own fond fancies, fell into thoughts of seeking blood-revenge. And since he knew naught of the details of the events, the absolute autocracy of the Amír-Nizám, his unbridled power, and sole authority; nor [was aware] that this sentence had been promulgated absolutely without the cognizance of the Royal Court, and that the Prime Minister had presumptuously issued the order on his own sole responsibility; since, on the contrary, he supposed that agreeably to ordinary custom and usage the attendants of the court had had a share in, and a knowledge of this sentence, therefore, [impelled by] folly, frenzy, and his evil star, nay, by sheer madness, he rose up from Tabríz and came straight to Tihrán, one other person being his accomplice. Then, since the Royal Train had its abode in Shimírán, he thither directed his steps. God is our refuge! By him was wrought a deed so presumptuous that the tongue is unable to declare and the pen loath to describe it. Yet to God be praise and thankfulness that this madman had charged his pistol with shot, imagining this to be preferable and superior to all projectiles.
