Sahih Bukhari

Narated By Abu Humaid : The Prophet 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?"
