September 9

Undeterred, unruffled, exultant with joy, Táhirih arose, [1] and, without the least premeditation and in a language strikingly resembling that of the Qur’án, delivered a fervid and eloquent appeal to the remnant of the assembly, ending it with this bold assertion: “I am the Word which the Qá’im is to utter, the Word which shall put to flight the chiefs and nobles of the earth!” Thereupon, she invited them to embrace each other and celebrate so great an occasion.

On that memorable day the “Bugle” mentioned in the Qur’án was sounded, the “stunning trumpet-blast” was loudly raised, and the “Catastrophe” came to pass. The days immediately following so startling a departure from the time-honored traditions of Islám witnessed a veritable revolution in the outlook, habits, ceremonials and manner of worship of these hitherto zealous and devout upholders of the Muhammadan Law.
