question #3 Sahih al-Bukhari 3797, Book 63, Hadith 22 : What is the role of the Emigrants and the Ansar in the context of early Islamic history?

Allah’s Messenger (ﷺ) came to us while we were digging the trench and carrying out the earth on our backs.
Allah’s Messenger (ﷺ) then said, “O Allah ! There is no life except the life of the Hereafter, so please forgive
the Emigrants and the Ansar.”
