It was narrated that Abu Taiyah said:
"I heard Anas Bin Malik say: The Messenger of Allah ﷺ used to mix with us so much that he said to a little brother of mine: "O Abu `Umair, what happened to the Nughair (one of the narrators Waki` said that it means a bird that he used to play with)."

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ شُعْبَةَ، عَنْ أَبِي التَّيَّاحِ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ كَانَ رَسُولُ اللَّهِ ـ ﷺ ـ يُخَالِطُنَا حَتَّى يَقُولَ لأَخٍ لِي صَغِيرٍ " يَا أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ " . قَالَ وَكِيعٌ يَعْنِي طَيْرًا كَانَ يَلْعَبُ بِهِ .
