Bahaï is the capital of the Ennedi Est department of Chad. It is located in the Ennedi Region, which was formed in 2008 from the Ennedi Est and Ennedi Ouest departments of the former Bourkou-Ennedi-Tibesti region.

The Bahá'í Faith ( Bahá'iyyat, Bahá'iyya ) is a monotheistic religion which emphasizes the spiritual unity of all humankind. Three core principles establish a basis for Bahá'í teachings and doctrine: the unity of God, that there is only one God who is the source of all creation; the unity of religion, that all major religions have the same spiritual source and come from the same God; and the unity of humanity, that all humans have been created equal, coupled with the unity in diversity, that diversity of race and culture are seen as worthy of appreciation and acceptance. According to the Bahá'í Faith's teachings, the human purpose is to learn to know and to love God through such methods as prayer, reflection and being of service to humanity.
