From Sahih Muslim (Hadith 6426):
Abu Usaid Ansari reported that he heard Allah's Messenger (ﷺ) as saying:The worthiest of the Ansar or the worthiest of the settlements and the clans of Ansar; the rest of the hadith is the same, but there is no mention of the story of Sa'd b. 'Ubida (Allah be pleased with him)
