“ … in the Lawh-i-Ra'ís, Bahá'u'lláh, recalling His conversation with the Turkish officer charged with the task of enforcing His banishment to the fortress-town of 'Akká, has written: "There is a matter, which, if thou findest it possible, I request thee to submit to His Majesty the Sultan, that for ten minutes this Youth be enabled to meet him, so that he may demand whatsoever he deemeth as a sufficient testimony and regardeth as proof of the veracity of Him Who is the Truth. Should God enable Him to produce it, let him, then, release these wronged ones, and leave them to themselves." "He promised," Bahá'u'lláh adds in that Tablet, "to transmit this message, and to give Us his reply. We received, however, no news from him. Although it becometh not Him Who is the Truth to present Himself before any person, inasmuch as all have been created to obey Him, yet in view of the condition of these little children and the large number of women so far removed from their friends and countries, We have acquiesced in this matter. In spite of this nothing hath resulted. Umar himself is alive and accessible. Inquire from him, that the truth may be made known unto you."
