Abu 'Umair, what has the sparrow done? He (Anas) said that he had been playing with that.  

كَانَ رَسُولُ اللَّهِ ﷺ أَحْسَنَ النَّاسِ خُلُقًا وَكَانَ لِي أَخٌ يُقَالُ لَهُ أَبُو عُمَيْرٍ قَالَ أَحْسِبُهُ قَالَ كَانَ فَطِيمًا قَالَ فَكَانَ إِذَا جَاءَ رَسُولُ اللَّهِ ﷺ فَرَآهُ قَالَ أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ قَالَ فَكَانَ يَلْعَبُ بِهِ  

The Prophet ﷺ was the best of all the people in character. I had a brother called Abu ʿUmar, who, I think, had been newly weaned. Whenever he (that child) was brought to the Prophet ﷺ the Prophet ﷺ used to say, "O Abu ʿUmar! What did Al-Nughair (nightingale) (do)?" It was a nightingale with which he used to play. Sometimes the time of the Prayer became due while he (the Prophet) was in our house. He would order that the carpet underneath him be swept and sprayed with water, and then he would stand up (for the prayer) and we would line up behind him, and he would lead us in prayer. (Using translation from Bukhārī 6203)   

كَانَ رَسُولُ اللهِ ﷺ أَحْسَنَ النَّاسِ خُلُقًا وَكَانَ لِي أَخٌ يُقَالُ لَهُ أَبُو عُمَيْرٍ أَحْسَبُهُ قَالَ فَطِيمٌ فَكَانَ إِذَا جَاءَ قَالَ أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ؟ كَانَ يَلْعَبُ بِهِ وَرُبَّمَا حَضَرَتِ الصَّلَاةُ وَهُوَ فِي بَيْتِنَا فَيَأْمُرُ بِالْبِسَاطِ الَّذِي تَحْتَهُ فَيُكْنَسُ وَيُنْضَحُ ثُمَّ يَقُومُ وَنَقُومُ خَلْفَهُ فَيُصَلِّي بِنَا
