Consequences of rejecting the Message of God brought by Bahá’u’lláh: --> Násiri’d-Dín Sháh – the “Prince of Oppressors”

…the fate that has overtaken those kings, ministers and ecclesiastics, in the East as well as in the West, who have, at various stages of Bahá’u’lláh’s ministry, either deliberately persecuted His Cause, or have neglected to heed the warnings He had uttered, or have failed in their manifest duty to respond to His summons or to accord Him and His message the treatment they deserved, particular attention…

The vain and despotic Náṣiri’d-Dín Sháh, denounced by Bahá’u’lláh as the “Prince of Oppressors”; of whom He had written that he would soon be made “an object-lesson for the world”; whose reign was stained by the execution of the Báb and the imprisonment of Bahá’u’lláh; who had persistently instigated his subsequent banishments to Constantinople, Adrianople and Akká; who, in collusion with a vicious sacerdotal order, had vowed to strangle the Faith in its cradle, was dramatically assassinated, in the shrine of Sháh ‘Abdu’l-‘Aẓím, on the very eve of his jubilee, which, as ushering in a new era, was to have been celebrated with the most elaborate magnificence, and was to go down in history as the greatest day in the annals of the Persian nation. The fortunes of his house thereafter steadily declined, and finally through the scandalous misconduct of the dissipated and irresponsible Aḥmad Sháh, led to the eclipse and disappearance of the Qájár dynasty.
