Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَدْخُلُ عَلَيْنَا وَلِي أَخٌ صَغِيرٌ يُكْنَى أَبَا عُمَيْرٍ وَكَانَ لَهُ نُغَرٌ يَلْعَبُ بِهِ فَمَاتَ فَدَخَلَ عَلَيْهِ النَّبِيُّ صلى الله عليه وسلم ذَاتَ يَوْمٍ فَرَآهُ حَزِينًا فَقَالَ " مَا شَأْنُهُ " . قَالُوا مَاتَ نُغَرُهُ فَقَالَ " يَا أَبَا عُمَيْرٍ مَا فَعَلَ النُّغَيْرُ " .
The Messenger of Allah (May peace be upon him) used to come to visit us. I had a younger brother who was called Abu ‘Umair by Kunyah (surname). He had a sparrow with which he played, but it died. So one day the prophet (May peace be upon him) came to see him and saw him grieved. He asked: What is the matter with him? The people replied: His sparrow has died. He then said: Abu ‘Umair! What has happened to the little sparrow?
