The Prophet ﷺ said, "The best of the Ansar's families (homes) are those of Banu An-Najjar and then (those of) Banu ʿAbdul Ash-hal, then (those of) Banu Al-Harith bin Al-Khazraj and then (those of) Banu Saʿida; nevertheless, there is good in all the families (houses) of the Ansar." On this, Saʿd (bin Ubada) said, "I see that the Prophet ﷺ has preferred some people to us." Somebody said (to him), "No, but he has given you superiority to many." (Hadith similar to above with a different chain) (Using translation from Bukhārī 3789)  

قَالَ رَسُولُ اللهِ ﷺ «خَيْرُ الْأَنْصَارِ بَنُو النَّجَّارِ ثُمَّ بَنُو عَبْدِ الْأَشْهَلِ ثُمَّ بَنُو سَاعِدَةَ ثُمَّ بَنُو الْحَارِثِ بْنِ الْخَزْرَجِ»
