Queen Elizabeth is, supposedly, related to the Hashmite descendants of Mohamed through her grandfather. Her father, however, had rejected Islam.
Ali Gomaa: Queen Elizabeth a Hashemite of Al al-Bayt
JANUARY 18, 2015
In an interview on an Egyptian satellite TV, Juma, allegations by Egypt’s former Mufti, Sheikh Ali Gomaa, of the current queen of Britain, that Elizabeth was a confirmed Hashemite from the Prophet Muhammad, peace be upon him, that the books exist to prove and confirm this.
She is descended from Mohammed (and Genghis Khan, Dracula’s brother etc) in this case through the Spanish royals who’d intermarried with the former Arab rulers.
Also, interestingly, the Khazar royals through a Hungarian link.
