Hazrat Abu Huraira (may Allah be pleased with him) narrated that the Noble Prophet (peace and blessings be upon him) said: In this (matter of caliphate), people follow the Quraysh; the common Muslims follow the Qurayshi Muslims just as their common disbelievers have always followed the Qurayshi disbelievers.

Hazrat Ibn Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: This caliphate will remain in the hands of the Quraysh as long as there are two men among them.

Hazrat Jabir bin Samurah (may Allah be pleased with him) narrated that I heard the Noble Prophet (peace and blessings be upon him) say, "There will be twelve leaders (amirs) in my ummah." Then he said something which I did not hear. Later, my father informed me that he (the Prophet) said, "All of them will be from the Quraysh."
