حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ قَالَ: كَانَ النَّبِيُّ صلى الله عليه وسلم يَدْخُلُ عَلَيْنَا، وَلِي أَخٌ صَغِيرٌ يُكَنَّى: أَبَا عُمَيْرٍ، وَكَانَ لَهُ نُغَرٌ يَلْعَبُ بِهِ فَمَاتَ، فَدَخَلَ النَّبِيُّ صلى الله عليه وسلم فَرَآهُ حَزِينًا، فَقَالَ: مَا شَأْنُهُ؟ قِيلَ لَهُ: مَاتَ نُغَرُهُ، فَقَالَ: يَا أَبَا عُمَيْرٍ، مَا فَعَلَ النُّغَيْرُ؟.
Anas said, "The Prophet, may Allah bless him and grant him peace, visited us. I had a young brother who used the kunya of Abu 'Umayr. He had a sparrow which he used to play with it and it had died. The Prophet, may Allah bless him and grant him peace, came it and saw that he was sad. He asked, 'What is wrong with him?' He was told, 'His sparrow has died.' The Prophet said, 'Abu 'Umayr, what has happened to the little sparrow?'"
