Twelve caliphs & all of them will belong to Quraysh.

Sunan of Abu-DawoodHadith 4266 Narrated byJabir ibn Samurah
The Prophet (peace be upon him) said: The religion will continue to be established till
there are twelve caliphs over you, and the whole community will agree on each of them. I then heard from the Prophet (peace be upon him) some remarks
which I could not understand. I asked my father: What is he saying: He said: all of them will belong to Quraysh.

Sahih Al-Bukhari HadithHadith 9.329 Narrated byJabir bin Samura
I heard the Prophet saying, “There will be twelve Muslim rulers (who will rule all the Islamic world).” He then said a sentence which I did not hear. My father
said, “All of them (those rulers) will be from Quraish.”
