The sign of a hypocrite is the hatred against the Ansar and the sign of a believer is the love for the Ansar.  

قَالَ رَسُولُ اللَّهِ ﷺ آيَةُ الْمُنَافِقِ بُغْضُ الأَنْصَارِ وَآيَةُ الْمُؤْمِنِ حُبُّ الأَنْصَارِ  

The love of the Ansar is the sign of faith and hatred against them is the sign of dissemblance.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ حُبُّ الأَنْصَارِ آيَةُ الإِيمَانِ وَبُغْضُهُمْ آيَةُ النِّفَاقِ  

"None but the believer loves them, none but the hypocrite hates them. He who loves them loves Allah and he who hates them hates Allah." I (the narrator) said: Did you hear this hadith from al-Bara'? He said: He narrated it to me.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ فِي الأَنْصَارِ لاَ يُحِبُّهُمْ إِلاَّ مُؤْمِنٌ وَلاَ يُبْغِضُهُمْ إِلاَّ مُنَافِقٌ مَنْ أَحَبَّهُمْ أَحَبَّهُ اللَّهُ وَمَنْ أَبْغَضَهُمْ أَبْغَضَهُ اللَّهُ قَالَ شُعْبَةُ قُلْتُ لِعَدِيٍّ سَمِعْتَهُ مِنَ الْبَرَاءِ قَالَ إِيَّاىَ حَدَّثَ  

A person who believes in Allah and the Last Day never nurses a grudge against the Ansar.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يُبْغِضُ الأَنْصَارَ رَجُلٌ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ  

The person who believes in Allah and the Last Day never nurses a grudge against the Ansar.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يُبْغِضُ الأَنْصَارَ رَجُلٌ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ  

'Ali observed: By Him Who split up the seed and created something living, the Apostle (may peace and blessings be upon him) gave me a promise that no one but a believer would love me, and none but a hypocrite would nurse grudge against me.  

عَلِيٌّ وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ إِنَّهُ لَعَهْدُ النَّبِيِّ الأُمِّيِّ ﷺ إِلَىَّ أَنْ لاَ يُحِبَّنِي إِلاَّ مُؤْمِنٌ وَلاَ يُبْغِضَنِي إِلاَّ مُنَافِقٌ
