question #1 Sahih al-Bukhari 5300, Book 68, Hadith 49 : Which families among the Ansar were considered the best according to the Prophet Muhammad (ﷺ)?

Allah’s Messenger (ﷺ) said, “Shall I tell you of the best families among the Ansar?” They (the people) said,
“Yes, O Allah’s Messenger (ﷺ)!” The Prophet (ﷺ) said, “The best are Banu- An-Najjar, and after them are Banu
`Abdil Ash-hal, and after them are Banu Al-Harith bin Al-Khazraj, and after them are Banu Sa`ida.”
The Prophet (ﷺ) then moved his hand by closing his fingers and then opening them like one throwing
something, and then said, “Anyhow, there is good in all the families of the Ansar. ”
