Musnad Ahmad

It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Shall I not tell you which is the best house among the houses of the Ansar?" The house of Banu Najjar. Then he said: "Shall I tell you who are the best people after them?" The people said, "Why not." He said: "The Banu Abd al-Ashhal." Then he said: "Shall I tell you who are the best people after them?" The people said, "Why not." He said: "The Banu Harith bin Khazraj." Then he said: "Shall I tell you who are the best people after them?" The people said, "Why not." He said: "The Banu Sa'idah." Then he raised his voice and said: "There is goodness in every house of the Ansar."
