The following is an account recorded in Nabil’s Narrative/The Dawn Breakers, translated by the Guardian, Shoghi Effendi.
When Bahá’u’lláh was still a child, the Vazír, His father, dreamed a dream. Bahá’u’lláh appeared to him swimming in a vast, limitless ocean. His body shone upon the waters with a radiance that illumined the sea. Around His head, which could distinctly be seen above the waters, there radiated, in all directions, His long, jet-black locks, floating in great profusion above the waves. As he dreamed, a multitude of fishes gathered round Him, each holding fast to the extremity of one hair. Fascinated by the effulgence of His face, they followed Him in whatever direction He swam. Great as was their number, and however firmly they clung to His locks, not one single hair seemed to have been detached from His head, nor did the least injury affect His person. Free and unrestrained, He moved above the waters and they all followed Him.
The Vazír, greatly impressed by this dream, summoned a soothsayer, who had achieved fame in that region, and asked him to interpret it for him. This man, as if inspired by a premonition of the future glory of Bahá’u’lláh, declared: “The limitless ocean that you have seen in your dream, O Vazír, is none other than the world of being. Single-handed and alone, your son will achieve supreme ascendancy over it. Wherever He may please, He will proceed unhindered. No one will resist His march, no one will hinder His progress. The multitude of fishes signifies the turmoil which He will arouse amidst the peoples and kindreds of the earth. Around Him will they gather, and to Him will they cling. Assured of the unfailing protection of the Almighty, this tumult will never harm His person, nor will His loneliness upon the sea of life endanger His safety.”
That soothsayer was subsequently taken to see Bahá’u’lláh. He looked intently upon His face, and examined carefully His features. He was charmed by His appearance, and extolled every trait of His countenance. Every expression in that face revealed to his eyes a sign of His concealed glory. So great was his admiration, and so profuse his praise of Bahá’u’lláh, that the Vazír, from that day, became even more passionately devoted to his son. The words spoken by that soothsayer served to fortify his hopes and confidence in Him. Like Jacob, he desired only to ensure the welfare of his beloved Joseph, and to surround Him with his loving protection.
