This distinguished man, Mullá Muhammad-‘Alí, [Nabíl of Qá’in was his title] was one of those whose hearts were drawn to Bahá’u’lláh before the Declaration of the Báb; it was then that he drank the red wine of knowledge from the hands of the Cupbearer of grace. It happened that a prince, who was the son of Mír Asadu’lláh Khán, prince of Qá’in, was commanded to remain as a political hostage in Tihrán. He was young, far away from his loving father, and Mullá Muhammad-‘Alí was his tutor and guardian. Since the youth was a stranger in Tihrán, the Blessed Beauty showed him special kindness. Many a night the young prince was Bahá’u’lláh’s guest at the mansion, and Mullá Muhammad-‘Alí would accompany him. This was prior to the Declaration of the Báb.

It was then that this chief of all trusted friends was captivated by Bahá’u’lláh, and wherever he went, spread loving praise of Him. After the way of Islám, he also related the great miracles which he had, with his own eyes, seen Bahá’u’lláh perform, and the marvels he had heard. He was in ecstasy, burning up with love. In that condition, he returned to Qá’in with the prince.

Later on that eminent scholar, Áqá Muhammad of Qá’in (whose title was Nabíl-i-Akbar) was made a mujtahid, a doctor of religious law, by the late Shaykh Murtadá; he left, then, for Baghdád, became an ardent follower of Bahá’u’lláh, and hastened back to Persia. The leading divines and mujtahids were well aware of and acknowledged his vast scholarly accomplishments, the breadth of his learning, and his high rank. When he reached Qá’in, he began openly to spread the new Faith. The moment Mullá Muhammad-‘Alí heard the name of the Blessed Beauty, he immediately accepted the Báb. “I had the honor,” he said, “of meeting the Blessed Beauty in Tihrán. The instant I saw Him, I became His slave.”
