Fatima was another name for Al-lat.  She also is called Creatress, Source of the Sun, and Tree of Paradise, the Tree of Life. Fatima is said to have existed from the beginning of the material world...like Sophia, a goddess in the Old Testament we will meet in a minute.
Mohammed named his own daughter after Goddess Fatima, but her worship still got brutally stamped out.
Sufis have tried to hang onto Fatima, however, and to the sacred marriage. 
They are forced to use code words though, since Sufism is part of Islam, and revering the sacred feminine will get you killed even today, in Islamic countries.
