Anas b. Malik reported that Allah's Messenger (ﷺ) had the sublimest character among mankind. I had a brother who was called Abu 'Umair. I think he was weaned. When Allah's Messenger (may peace he upon him) came to our house he saw him, and said:
حَدَّثَنَا أَبُو الرَّبِيعِ، سُلَيْمَانُ بْنُ دَاوُدَ الْعَتَكِيُّ حَدَّثَنَا عَبْدُ الْوَارِثِ ، حَدَّثَنَا أَبُو التَّيَّاحِ ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ ، ح وَحَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا عَبْدُ الْوَارِثِ ، عَنْ أَبِي التَّيَّاحِ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَحْسَنَ النَّاسِ خُلُقًا وَكَانَ لِي أَخٌ يُقَالُ لَهُ أَبُو عُمَيْرٍ - قَالَ أَحْسِبُهُ قَالَ - كَانَ فَطِيمًا - قَالَ - فَكَانَ إِذَا جَاءَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَرَآهُ قَالَ " أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ " . قَالَ فَكَانَ يَلْعَبُ بِهِ .
Abu 'Umair, what has the sparrow done? He (Anas) said that he had been playing with that.
