The Twin Holy Days, namely the anniversaries of the birthdays of the Báb and Bahá’u’lláh, are celebrated on two consecutive days in October / November (ʻIlm / Qudrat).
Bahá’u’lláh was born into wealthy nobility. He was offered a high-ranking government position, refusing it, instead devoting Himself to serving God and the helping of the poor and the sick.
Bahá’u’lláh was born in the capital Persia, Tihran, in 1817 with the given name of Mírzá Ḥusayn ‘Alí. As He became a religious leader with a following, the authorities became concerned and decided to exile Him, first from Persia to Iraq and Turkey, and eventually to Palestine. He would remain a prisoner of the Persian and Ottoman empires until the end of His life.
However, this did not make Him desponded, as Bahá’u’lláh continued to spread the divine message:
”The Great Being saith: Blessed and happy is he that ariseth to promote the best interests of the peoples and kindreds of the earth. In another passage He hath proclaimed: It is not for him to pride himself who loveth his own country, but rather for him who loveth the whole world. The earth is but one country, and mankind its citizens.”
