Rahmat is one of the Bahá'í festivals, adherents of the youngest major religion in the world, with their own scriptures. The yearbook of the British Encyclopedia at the end of the twentieth century estimated the number of followers of the doctrine at 6, 67 million people.
The forerunners of the emergence of Bahá'ís were the events that took place on the territory of modern Iran in the middle of the 19th century. The young man Sayyid Ali-Muhammad, who remained in history under the name Bab, proclaimed himself the bearer of divine revelation and predicted that the messenger of God would soon descend on Earth. The Islamic clergy did not like such sermons and they put pressure on the Persian government to the point that after six years of persecution, the Bab was shot. In addition, about 20 thousand of his followers were executed throughout Persia.
One of the Bab's disciples, the Persian aristocrat Mirza Hussein Ali, was not executed, but lost all his property and was exiled to Iraq. There, in Tehran, he declared himself the messenger of God, about whose coming the Bab spoke. Then he was exiled first to Constantinople, then to Adrianople and further to Akko, a city on the territory of modern Israel. By that time, many rulers of that time knew him by the name Bahá'u'lláh, which means God's glory. He wrote letters to them, urging them to recognize him as the Promised One, predicted by all religions.
Bahá'u'lláh became the author of sacred texts and the founder of the Bahá'í religion. It is based on the unity of God for all nations. All major world religions originated from one source and are constituent parts of a single Faith. The time has come for humanity to unite into a single peaceful global society.
At present, there are followers of the teachings of Bahá'u'lláh on all continents of the world. The Bahá'ís have a nineteen-month calendar, and every nineteenth day there are holidays, the structure of which was determined by the great-grandson of Bahá'u'lláh, Shoghi Efendi. They consist of spiritual, administrative and social parts.
On June 24, 2012, Bahá'ís celebrate the holiday of the Nineteenth Day - Rahmat. On this day, believers read prayers, reflect on the sublime, deal with issues of community and world order, in the social part they are engaged in communication with each other.
