BUKHARI 3783:
from al-Barāʾ —
I heard the Prophet ﷺ saying (or the Prophet ﷺ said), "None loves the Ansar but a believer, and none hates them but a hypocrite. So Allah will love him who loves them, and He will hate him who hates them."
البخاري ٣٧٨٣:
عن البراء —
سَمِعْتُ النَّبِيَّ ﷺ أَوْ قَالَ قَالَ النَّبِيُّ ﷺ الأَنْصَارُ لاَ يُحِبُّهُمْ إِلاَّ مُؤْمِنٌ وَلاَ يُبْغِضُهُمْ إِلاَّ مُنَافِقٌ فَمَنْ أَحَبَّهُمْ أَحَبَّهُ اللَّهُ وَمَنْ أَبْغَضَهُمْ أَبْغَضَهُ اللَّهُ
