In the days of Bahá’u’lláh, during the worst times in the Most Great Prison, they would not permit any of the friends either to leave the Fortress or to come in from the outside. … [two Azalís] lived by the second gate of the city, and watched there at all times, day and night. Whenever they spied a Bahá’í traveler they would hurry away to the Governor and tell him that the traveler was bringing in letters and would carry the answers back. The Governor would then arrest the traveler, seize his papers, jail him, and drive him out. This became an established custom with the authorities and went on for a long time—indeed, for nine years until, little by little, the practice was abandoned.
It was at such a period that the Afnán, Hájí Mírzá Muhammad-‘Alí—that great bough of the Holy Tree  — journeyed to Akká, coming from India to Egypt, and from Egypt to Marseilles. One day I was up on the roof of the caravanserai. Some of the friends were with me and I was walking up and down. It was sunset. At that moment, glancing at the distant seashore, I observed that a carriage was approaching. “Gentlemen,” I said, “I feel that a holy being is in that carriage.” It was still far away, hardly within sight.
“Let us go to the gate,” I told them. “Although they will not allow us to pass through, we can stand there till he comes.” I took one or two people with me and we left.
At the city gate, I called to the guard, privately gave him something and said: “A carriage is coming in and I think it is bringing one of our friends. When it reaches here, do not hold it up, and do not refer the matter to the Governor.” He put out a chair for me and I sat down.
By this time the sun had set. They had shut the main gate, too, but the little door was open. The gatekeeper stayed outside, the carriage drew up, the gentleman had arrived. What a radiant face he had! He was nothing but light from head to foot. Just to look at that face made one happy; he was so confident, so assured, so rooted in his faith, and his expression so joyous. He was truly a blessed being. He was a man who made progress day by day, who added, every day, to his certitude and faith, his luminous quality, his ardent love. He made extraordinary progress during the few days that he spent in the Most Great Prison. The point is that when his carriage had come only part of the way from Haifa to Akká, one could already perceive his spirit, his light.
