Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Shall I not tell you about the best households among the Ansar?" The people replied: "Yes, indeed." The Prophet (peace and blessings be upon him) said: "The household of Banu Najjar, then the household of Banu Abd al-Ashhal, then the household of Banu Harith bin Khazraj, then the household of Banu Sa'idah. However, there is goodness in every household of the Ansar."
