´Narrated Anas bin Malik:` that the Messenger of Allah (ﷺ) said: "The Ansar are my close ones and my elite. Indeed the people shall increase and they shall dwindle, so accept from those who do good among them, and overlook those who do bad among them."

´Narrated Abu Usaid As-Sa'idi:` that the Messenger of Allah (ﷺ) said: "The Best houses of the Ansar are the houses of Banu An-Najjar, then the house of Banu 'Abdul-Ashhal, then Banu Al-Harith bin Al-Khazraj, then Banu Sa'idah. And in all of the houses of the Ansar there is good." So Sa'd said: "I do not see except that the Prophet (ﷺ) has preferred everyone over us." So it was said: "He preferred you over many."
