The Báb sent two messengers to Muhammad Shah, the King of Persia – one messenger with “a truly resplendent Tablet”, and another with “epistles” revealed by Him

This is an Epistle from Him Who is the true, the undoubted Leader. Herein is revealed the law of all things for those who fain would heed His Call or wish to be reckoned among them that are guided aright. Herein is enshrined the law of all things for such as would bear witness to the Revelation of thy Lord in accordance with this clear balance. Verily the ordinances of God concerning all things were formerly set forth in eloquent Arabic. Indeed those whose souls have been created through the splendor of the light of thy Lord recognize the Truth and are numbered with such as faithfully obey the One True God and are well assured.…

O Muhammad! The Decree of thy Lord was fulfilled four years ago; and ever since the inception of the Cause of thy Lord I have warned thee to fear God and not to be of the ignorant. I dispatched a messenger unto thee with a truly resplendent Tablet, but the followers of the devil turned him away disdainfully and interposed themselves between him and thee. They expelled him from the land whereof thou art the undisputed sovereign. Thus hath the good of this world and of the next escaped thee, unless thou submit to the commandment ordained by God and be of them that are rightly guided.

circa 1847:The Báb challenged the King of Persia, Muhammad Shah, to summon all the divines so He could prove the truth of His Mission

Muhammad Shah

If thou art not apprehensive that the truth might be revealed and the works of the ungodly be brought to naught, why summonest thou not the divines of the land, and then summon Me, so that I may confound them forthwith, even as those disbelievers whom I have previously confounded? This is My sure testimony unto thee and unto them, if they speak the truth. Summon thou all of them. Should they then be able to utter words like unto this, thou wouldst know that their cause is worthy of attention. Nay, by the righteousness of My Lord! They are bereft of power, nor are they endued with perception. They professed faith in the past without understanding its significance, then later they repudiated the Truth; for they are devoid of discernment.
