Al-Lu'lu Wal-Marjan 1195 — The Book of Al-Imâra (Concerning with ruling etc.)

Jabir bin Samurah Narrated from:

I heard the Prophet صلى الله عليه وسلم saying, "There will be twelve Muslim rulers (who will rule all the Islâmic world)." He then said a sentence which I did not hear. My father said he said, "All of them (those rulers) will be from Quraish." ( Sahih Al-Bukhâri, Hadîth No. 329, Vol. 9)
