The story of Yakub creating the 'white race' is a theological belief specific to the Nation of Islam, not a scientific or historically accepted account of human origins.
In the teachings of the Nation of Islam, especially as taught by Wallace Fard Muhammad and Elijah Muhammad, Yakub is described as a Black scientist who lived about 6,600 years ago on the island of Patmos. According to this doctrine, Yakub used selective breeding to create a new race of people with lighter skin, whom he intended to rule the world for a period of time. This narrative is a foundational part of their cosmology and understanding of racial history. It's important to understand that this is a specific religious doctrine, not a claim supported by archaeology, genetics, or any mainstream historical or scientific field. It serves as an allegorical explanation for racial differences and power dynamics within the Nation of Islam's worldview.
