The Messenger of Allah ﷺ said, "Shall I not tell you about the best of the houses of the Ansar, or about the best of the Ansar?"They replied, "Of course, Messenger of Allah."He said, "Banu al-Najjar, then those who follow them, Banu Abd al-Ashhal, then those who follow them, Banu Harith bin Khazraj, then those who follow them, Banu Saidah."Then he gestured with his hand, closing his fingers and then opening them like one casting something forth, and said, "Yet there is good in all the houses of the Ansar."
