Narrated Abu Usaid: Allah's Apostle said, The best of the Ansar's houses are those of Bani An-Najjar, then those of Bani `Abdul Ash-hal, then those of Bani Al-Harith bin Al-Khazraj, then those of Bani Saida; but there is goodness in all the houses of the Ansar. Sa`d bin Ubada who was one of those who embraced Islam early, said, I see that Allah's Apostle is giving others superiority above us. Some people said to him, But he has given you superiority above many other people.
