At the start of human history, a variety of types of black people inhabited the moon; when a black "god-scientist" became frustrated that all those living on the moon did not speak one language, he blew up the moon. A piece of this destroyed moon became the Earth, which was then populated by a community of surviving, morally righteous black people, some of whom settled in the city of Mecca. Yakub was born a short distance outside the city, and was among the third of original black people who were discontented with life in this society. A member of the Meccan branch of the Tribe of Shabazz, Yakub acquired the nickname "big head", because of his unusually large head and arrogance. At the age of six, he discovered the law of attraction and repulsion by playing with magnets made of steel.

This insight led to a plan to create a new people. He "saw an unlike human being, made to attract others, who could, with the knowledge of tricks and lies, rule the original black man". By the age of 18, he had exhausted all knowledge in the universities of Mecca. He then discovered that the original black man contained both a "black germ" and a "brown germ". With 59,999 followers, he went to an "isle in the Aegean Sea called Pelan", which Muhammad identified as modern-day Patmos. Once there, he established a despotic regime, starting to breed out the black traits of his followers, killing all darker babies, and succeeded in creating a brown race after 200 years.

Yakub died at the age of 150, but his followers carried on his work. After 600 years of this deliberate eugenics system, the white race was created.
