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."  

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  

The Prophet ﷺ said, "The sign of Belief is to love the Ansar, and the sign of hypocrisy is to hate the Ansar."  

عَنِ النَّبِيِّ ﷺ قَالَ آيَةُ الإِيمَانِ حُبُّ الأَنْصَارِ وَآيَةُ النِّفَاقِ بُغْضُ الأَنْصَارِ
