It has been reported on the authority of Jabir b. Samura who said:
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، حَدَّثَنَا ابْنُ عَوْنٍ ، ح وَحَدَّثَنَا أَحْمَدُ بْنُ عُثْمَانَ النَّوْفَلِيُّ ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا أَزْهَرُ ، حَدَّثَنَا ابْنُ عَوْنٍ ، عَنِ الشَّعْبِيِّ ، عَنْ جَابِرِ بْنِ سَمُرَةَ ، قَالَ انْطَلَقْتُ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَعِي أَبِي فَسَمِعْتُهُ يَقُولُ " لاَ يَزَالُ هَذَا الدِّينُ عَزِيزًا مَنِيعًا إِلَى اثْنَىْ عَشَرَ خَلِيفَةً " . فَقَالَ كَلِمَةً صَمَّنِيهَا النَّاسُ فَقُلْتُ لأَبِي مَا قَالَ قَالَ " كُلُّهُمْ مِنْ قُرَيْشٍ " .
I went with my father to the Messenger of Allah (may peeace be upon him) and I heard him say: This religion would continue to remain powerful and dominant until there have been twelve Caliphs. Then he added something which I couldn't catch on account of the noise of the people. I asked my father: What did he say? My father said: He has said that all of them will be from the Quraish.
