Sahih al-Bukhari 63:32
Narrated Abu Usaid:
Allah's Messenger (ﷺ) 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 Messenger (ﷺ) is giving others superiority above us." Some people said to him, "But he has given you superiority above many other people."

حَدَّثَنَا إِسْحَاقُ، حَدَّثَنَا عَبْدُ الصَّمَدِ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا قَتَادَةُ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ قَالَ أَبُو أُسَيْدٍ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " خَيْرُ دُورِ الأَنْصَارِ بَنُو النَّجَّارِ، ثُمَّ بَنُو عَبْدِ الأَشْهَلِ، ثُمَّ بَنُو الْحَارِثِ بْنِ الْخَزْرَجِ، ثُمَّ بَنُو سَاعِدَةَ وَفِي كُلِّ دُورِ الأَنْصَارِ خَيْرٌ ". فَقَالَ سَعْدُ بْنُ عُبَادَةَ ـ وَكَانَ ذَا قِدَمٍ فِي الإِسْلاَمِ ـ أَرَى رَسُولَ اللَّهِ صلى الله عليه وسلم قَدْ فَضَّلَ عَلَيْنَا. فَقِيلَ لَهُ قَدْ فَضَّلَكُمْ عَلَى نَاسٍ كَثِيرٍ.
