Frustrated in their designs, but unrelenting in their hostility, the assembled divines delegated the learned and devout Ḥájí Mullá Ḥasan-i-‘Ammú, recognized for his integrity and wisdom, to submit various questions to Bahá’u’lláh for elucidation. When these were submitted, and answers completely satisfactory to the messenger were given, Ḥájí Mullá Ḥasan, affirming the recognition by the ‘ulamás of the vastness of the knowledge of Bahá’u’lláh, asked, as an evidence of the truth of His mission, for a miracle that would satisfy completely all concerned. “Although you have no right to ask this,” Bahá’u’lláh replied, “for God should test His creatures, and they should not test God, still I allow and accept this request.... The ‘ulamás must assemble, and, with one accord, choose one miracle, and write that, after the performance of this miracle they will no longer entertain doubts about Me, and that all will acknowledge and confess the truth of My Cause. Let them seal this paper, and bring it to Me. This must be the accepted criterion: if the miracle is performed, no doubt will remain for them; and if not, We shall be convicted of imposture.” This clear, challenging and courageous reply, unexampled in the annals of any religion, and addressed to the most illustrious _Sh_í’ah divines, assembled in their time-honored stronghold, was so satisfactory to their envoy that he instantly arose, kissed the knee of Bahá’u’lláh, and departed to deliver His message. Three days later he sent word that that august assemblage had failed to arrive at a decision, and had chosen to drop the matter, a decision to which he himself later gave wide publicity, in the course of his visit to Persia, and even communicated it in person to the then Minister of Foreign Affairs, Mírzá Sa’íd _Kh_án. “We have,” Bahá’u’lláh is reported to have commented, when informed of their reaction to this challenge, “through this all-satisfying, all-embracing message which We sent, revealed and vindicated the miracles of all the Prophets, inasmuch as We left the choice to the ‘ulamás themselves, undertaking to reveal whatever they would decide upon.” “If we carefully examine the text of the Bible,” ‘Abdu’l-Bahá has written concerning a similar challenge made later by Bahá’u’lláh in the “Lawḥ-i-Sulṭán,” “we see that the Divine Manifestation never said to those who denied Him, ‘whatever miracle you desire, I am ready to perform, and I will submit to whatever test you propose.’ But in the Epistle to the _Sh_áh Bahá’u’lláh said clearly, ‘Gather the ‘ulamás and summon Me, that the evidences and proofs may be established.’”
