Bahá’u’lláh, the Prophet-Founder of the Bahá’í Faith, was born on November 12, 1817, in Tehran, Iran. This holy day is celebrated annually by Bahá’ís worldwide, often in conjunction with the Birth of the Báb. It is a time to reflect on Bahá’u’lláh’s life, teachings, and sacrifices, and to renew one’s commitment to the principles of unity, love, and service to humanity.
