"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 ʿUmair, what happened to the Nughair (one of the narrators Wakiʿ said that it means a bird that he used to play with)." (Using translation from Ibn Mājah 3720)
سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ رَسُولُ اللهِ ﷺ يُخَالِطُنَا حَتَّى يَقُولَ لِأَخٍ لِي صَغِيرٍ يَا أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ طَيْرٌ كَانَ يَلْعَبُ بِهِ قَالَ وَنُضِحَ بِسَاطٌ لَنَا قَالَ فَصَلَّى عَلَيْهِ وَصَفَّنَا خَلْفَهُ
