The Annwar said, "O Allah's Messenger (ﷺ)! Every prophet has his own followers and we have followed you. So will you invoke Allah to let our followers be considered from us (as Ansar too)?" So he invoked Allah accordingly.
Sahih al-Bukhari Book 63, Hadith 12
← Previous Hadith Once an Ansari woman, accompanied by a son of hers, came to Allah's Messenger (ﷺ). Allah's Messenger (ﷺ) spoke to her and said twice, "By Him in Whose Hand my life is, you are the most beloved people to me."

Sahih al-Bukhari Book 63, Hadith 11 Next Hadith → (A man from the Ansar) The Ansar said, "Every nation has followers and (O Prophet) we have followed you, so invoke Allah to let our followers be considered from us (as Ansar like ourselves)." So the Prophet (ﷺ) said, "O Allah! Let their followers be considered as Ansar like themselves."
