Sahih al-Bukhari · Book 65: Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh)) · "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)
Narrated Abu Huraira:
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.
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.
