Al-Adab Al-Mufrad, Book 20, Hadith 384 (English) ⓘ
Anas said, "The Prophet, may Allah bless him and grant him peace, came in and saw a son of Abu Talha's called Abu 'Umayr. He had a sparrow which he used to play with." He said, "Abu 'Umayr, what happened to (or where is) the little sparrow?'"
حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ قَالَ: دَخَلَ النَّبِيُّ صلى الله عليه وسلم فَرَأَى ابْنًا لأَبِي طَلْحَةَ يُقَالُ لَهُ: أَبُو عُمَيْرٍ، وَكَانَ لَهُ نُغَيْرٌ يَلْعَبُ بِهِ، فَقَالَ: يَا أَبَا عُمَيْرٍ، مَا فَعَلَ أَوْ، أَيْنَ، النُّغَيْرُ؟.
