The Guardian of the Bahá'í Faith states that Bahá'u'lláh visited Haifa four times. The first visit was of short duration, when He disembarked in 1868 from the Lloyd-Triestino steamer. The second visit was for just a few days, and He stayed in Bayt-i-Fanduq, a house in the German colony, part of which still stands today. There is a dated Tablet, in the handwriting of Mirza Aqa Jan, which indicates that Bahá'u'lláh was in Haifa in August 1883, probably the date of this second visit. The third visit was in 1890, and when Edward Granville Browne reached 'Akká, Bahá'u'lláh was in Haifa. In the course of this visit, He stayed, at first, near Bayt-i-Zahlan, near the town, and then He moved to a house in the German colony which was known as the Oliphant house. His tent was pitched on a piece of land opposite that house. His fourth and last visit was in the year 1891. This sojourn was the longest, and it was here in Haifa that members of the Afnan family met him when they came in July, as described in a later chapter. Bahá'u'lláh was then in Haifa for three months, staying in the house of Ilyas Abyad near the German colony, and His tent stood nearby.
