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. (Using translation from Muslim 1818b)   

قَالَ رَسُولُ اللهِ ﷺ النَّاسُ أَتْبَاعٌ لِقُرَيْشٍ فِيهَذَا الشَّأْنِ كُفَّارُهُمْ أَتْبَاعٌ لِكُفَّارِهِمْ وَمُسْلِمُوهُمْ أَتْبَاعٌ لِمُسْلِمِيهِمْ  

[Machine] The Messenger of Allah ﷺ said, "The people are followers of Quraysh in this matter, their best ones are followed by their best, and their worst ones are followed by their worst."  

قَالَ رَسُولُ اللهِ ﷺ النَّاسُ تَبَعٌ لِقُرَيْشٍ فِي هَذَا الْأَمْرِ خِيَارُهُمْ تَبَعٌ لِخِيَارِهِمْ وَشِرَارُهُمْ تَبَعٌ لِشِرَارِهِمْ  

The Prophet ﷺ said, "The tribe of Quraish has precedence over the people in this connection (i.e the right of ruling). The Muslims follow the Muslims amongst them, and the infidels follow the infidels amongst them. People are of different natures: The best amongst them in the pre-lslamic period are the best in Islam provided they comprehend the religious knowledge. You will find that the best amongst the people in this respect (i.e. of ruling) is he who hates it (i.e. the idea of ruling) most, till he is given the pledge of allegiance." (Using translation from Bukhārī 3495)  

وَقَالَ رَسُولُ اللهِ ﷺ النَّاسُ تَبَعٌ لِقُرَيْشٍ فِي هَذَا الشَّأْنِ مُسْلِمُهُمْ تَبَعٌ لِمُسْلِمِهِمْ وَكَافِرُهُمْ تَبَعٌ لِكَافِرِهِمْ  

"النَّاسُ تبعٌ لقريشٍ في هذا الأمرِ، فخيارهم تبع لخيارهم، وشرَارُهم تبَعٌ لشرارِهم" .  

"النَّاسُ تَبَعٌ لِقُرَيشٍ صَالِحُهُمْ تَبَعٌ لِصَالِحِهِمْ، وَشِرَارُهُمْ تَبَعٌ لِشِرَارِهِمْ".  

"عَنْ عَلِىٍّ قَالَ: سَمِعَتْ أُذُنَاىِ وَوَعَاهُ قَلْبِى مِنْ رَسُولِ الله ﷺ : النَّاسُ تَبَعٌ لِقُرَيْشٍ، خِيَارُهُمْ تَبَعًا لِخَيَارهِمْ، وَشِرَارُهُمْ تَبَعٌ لِشِرَارِهِمْ".
