The Prophet (ﷺ) said, "The tribe of Quraish has precedence over the people in this connection (i.e. the right of ruling). The Muslims follow the Muslims amongst them, and the infidels follow the infidels amongst them. People are (like) metals (of different natures): The best amongst them in the Pre-Islâmic Period of Ignorance are the best in Islâm provided they comprehend religious knowledge. You will find that the best amongst the people in this respect (i.e. of ruling) is he who hates it (i.e. the idea of ruling) most, till he is given the Bai'a (pledge)." [4:700-O.B]
