Bab was martyred because of the false utterances of Four Gates

This heedless and prattling (people) have understood this Revelation to be like unto the events of the past. Up to this moment they have not comprehended the significances of the "Day of God." They continue to deceive the people with the vain imaginings [awhaamaat] and the vain mentions that were current in the past. I swear by the righteousness of our Lord the Promised One! They have not uttered a word of truth. And now there are others now who intend to walk in the footsteps of those who were in the past Dispensation. If they had apprehended the meaning of the "Day of God" they would have utterly buried in the soil of oblivion such mentions as the mention of 'Wali' [=successor] and 'Wasi'[=appointee] and their like. They have not become cognizant of the fact that their Gates [abwaab] their Four Gates became the cause and reason of error. If those false utterances had not emanated from these day springs of falsity, the Primal Point, may the spirit all else but Him be a sacrifice unto Him, would not have been martyred.. And now they have attached themselves to that same system and wish to deceive the friends with those same mentions.
