What did the Prophet Muhammad (saw) say regarding the authority of ruling remaining with the Quraish?
 Narrated Muhammad bin Jubair bin Mut`im:                     That while he was with a delegation from Quraish to Muawiya, the latter heard the news that `Abdullah bin `Amr bin Al-`As said that there would be a king from the tribe of Qahtan. On that Muawiya became angry, got up and then praised Allah as He deserved, and said, "Now then, I have heard that some men amongst you narrate things which are neither in the Holy Book, nor have been told by Allah's Apostle. Those men are the ignorant amongst you. Beware of such hopes as make the people go astray, for I heard Allah's Apostle saying, 'Authority of ruling will remain with Quraish, and whoever bears hostility to them, Allah will destroy him as long as they abide by the laws of the religion.'
