Sahih Muslim 1818 b
It has been narrated on the authority of Hammam b. Munabbih who said:
This is one of the traditions narrated by Abu Huraira from the Messenger of Allah (ﷺ) who said: People are subservient to the Quraish: the Muslims among them being subservient to the Muslims among them, and the disbelievers among them being subservient to the disbelievers among them.
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ النَّاسُ تَبَعٌ لِقُرَيْشٍ فِي هَذَا الشَّأْنِ مُسْلِمُهُمْ تَبَعٌ لِمُسْلِمِهِمْ وَكَافِرُهُمْ تَبَعٌ لِكَافِرِهِمْ ‏"‏ ‏.‏
