"You (true believers in Islamic Monotheism, and real followers of Prophet Muḥammad pbuh and his Sunna) are the best of peoples ever raised up for mankind..." (V.3:110)
(7)
Sahih al-Bukhari 4557

Narrated Abu Huraira:

The Verse:--"You (true Muslims) are the best of peoples ever raised up for mankind." means, the best of peoples for the people, as you bring them with chains on their necks till they embrace Islam.

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، عَنْ سُفْيَانَ، عَنْ مَيْسَرَةَ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَة َ ـ رضى الله عنه ـ ‏{‏كُنْتُمْ خَيْرَ أُمَّةٍ أُخْرِجَتْ لِلنَّاسِ‏}‏ قَالَ خَيْرَ النَّاسِ لِلنَّاسِ، تَأْتُونَ بِهِمْ فِي السَّلاَسِلِ فِي أَعْنَاقِهِمْ حَتَّى يَدْخُلُوا فِي الإِسْلاَمِ‏.‏
