The Prophet ﷺ used to mix with us to the extent that he would say to a younger brother of mine, 'O Aba ʿUmair! What did the Nughair (a kind of bird) do?" (Using translation from Bukhārī 6129)
إِنْ كَانَ رَسُولُ اللهِ ﷺ لَيُخَالِطُنَا حَتَّى إِنْ كَانَ يَقُولُ لِأَخٍ لِي صَغِيرٍ «يَا أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ؟»
