Sahih Muslim 1821 d
The Book on Government
The people follow the Quraish and the Caliphate belongs to the Quraish
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ الأَزْدِيُّ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ يَزَالُ الإِسْلاَمُ عَزِيزًا إِلَى اثْنَىْ عَشَرَ خَلِيفَةً " . ثُمَّ قَالَ كَلِمَةً لَمْ أَفْهَمْهَا فَقُلْتُ لأَبِي مَا قَالَ فَقَالَ " كُلُّهُمْ مِنْ قُرَيْشٍ " .
It has been narrated on the authority of Jabir b. Samura who said: I heard the Messenger of Allah (ﷺ) say: Islam will continue to be triumphant until there have been twelve Caliphs. Then the Prophet (ﷺ) said something which I could not understand. I asked my father: What did he say? He said: He has said that all of them (twelve Caliphs) will be from the Quraish.
