The local Arabs of Acre did not embrace the new creed.

"Bahá'u'lláh's influence and renown among local Arabs was apparently considerable; however, they did not embrace the new creed. Nowadays there is not a single Bahá'í family of Arab origin in Acre. Local Arabs explain that at the time of Bahá'u'lláh's influence in Acre; in the competition between the Bahá'ís and the Shadliya, the latter predominated. Until now, Acre is a centre of the Shadliya."

(Erik Cohen, “The Baha'i Community of Acre”, Folklore Research Center Studies, vol. 3, 1972, pp. 119–141.)

It seems that not even the 'great majesty' of the 'Glory of God' in person convinced people from Acre of his claim as the new messenger of God. The Shadli's leadership was more convincing.
