← Previous Hadith 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."
