The Prophet ﷺ was passing through part of Medina when he came upon some young girls beating their tambourines and singing,"We are girls of Banu Najjar, what a fine neighbor Muhammad is."The Prophet ﷺ said, "Allah knows that I truly love you."
أن النبي ﷺ لو مر ببعض المدينة فإذا هو بجوار يضربن بدفهن، ويتغنين ويقلن: نحن جوار من بني النجار يا حبذا محمد من جار فقال النبي ﷺ: الله يعلم إني لأحبكن.
Ibn Majah (1899) narrated it from Hisham bin Ammar, who said, Isa bin Yunus told us, who said, Awf told us, from Thumama bin Abdullah, from Anas bin Malik, and he related it. Its isnad is hasan because of Thumama bin Abdullah, for his hadith is hasan.
