حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ دَاوُدَ، عَنِ الشَّعْبِيِّ، عَنْ جَابِرِ، بْنِ سَمُرَةَ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ يَزَالُ هَذَا الأَمْرُ عَزِيزًا إِلَى اثْنَىْ عَشَرَ خَلِيفَةً ‏"‏ ‏.‏ قَالَ ثُمَّ تَكَلَّمَ بِشَىْءٍ لَمْ أَفْهَمْهُ فَقُلْتُ لأَبِي مَا قَالَ فَقَالَ ‏"‏ كُلُّهُمْ مِنْ قُرَيْشٍ ‏"‏ ‏.‏

It has been narrated on the authority of Jabir b. Samura that the Prophet (PBUH) said: This order will continue to be dominant until there have been twelve Caliphs. The narrator says: Then he said something which I could not understand, and I said to my father: What did he say? My father told me that he said that all of them (Caliphs) would be from the Quraish.
