Narrated Abu Humaid:

The Prophet ﷺ said, "The best of the Ansar families (homes) are the families (homes) of Banu An-Najjar, and then that of Banu 'Abdul Ash-hal, and then that of Banu Al-Harith, and then that of Banu Saida;
and there is good in all the families (homes) of the Ansar." Sad bin 'Ubada followed us and said, "O Abu Usaid ! Don't you see that the Prophet compared the Ansar and made us the last of them in superiority? Then Sad met the Prophet and said, "O Allah's Apostle! In comparing the Ansar's families (homes) as to the degree of superiority, you have made us the last of them." Allah's Apostle replied, "Isn't it sufficient that you are regarded amongst the best?"

حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ، قَالَ حَدَّثَنِي عَمْرُو بْنُ يَحْيَى، عَنْ عَبَّاسِ بْنِ سَهْلٍ، عَنْ أَبِي حُمَيْدٍ، عَنِ النَّبِيِّ ﷺ قَالَ " إِنَّ خَيْرَ دُورِ الأَنْصَارِ دَارُ بَنِي النَّجَّارِ، ثُمَّ عَبْدِ الأَشْهَلِ، ثُمَّ دَارُ بَنِي الْحَارِثِ، ثُمَّ بَنِي سَاعِدَةَ، وَفِي كُلِّ دُورِ الأَنْصَارِ خَيْرٌ ". فَلَحِقْنَا سَعْدَ بْنَ عُبَادَةَ فَقَالَ أَبَا أُسَيْدٍ أَلَمْ تَرَ أَنَّ نَبِيَّ اللَّهِ ﷺ خَيَّرَ الأَنْصَارَ فَجَعَلَنَا أَخِيرًا فَأَدْرَكَ سَعْدٌ النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ، خُيِّرَ دُورُ الأَنْصَارِ فَجُعِلْنَا آخِرًا. فَقَالَ " أَوَلَيْسَ بِحَسْبِكُمْ أَنْ تَكُونُوا مِنَ الْخِيَارِ ".
