Hisham ibn 'Urwa reported that Ibn az-Zubayr was in Makka and the Companions of the Prophet, may Allah bless him and grant him peace, were carrying birds in cages.  

عَنْ هِشَامِ بْنِ عُرْوَةَ قَالَ كَانَ ابْنُ الزُّبَيْرِ بِمَكَّةَ وَأَصْحَابُ النَّبِيِّ ﷺ يَحْمِلُونَ الطَّيْرَ فِي الأَقْفَاصِ  

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?'"  

عَنْ أَنَسٍ قَالَ دَخَلَ النَّبِيُّ ﷺ فَرَأَى ابْنًا لأَبِي طَلْحَةَ يُقَالُ لَهُ أَبُو عُمَيْرٍ وَكَانَ لَهُ نُغَيْرٌ يَلْعَبُ بِهِ فَقَالَ يَا أَبَا عُمَيْرٍ مَا فَعَلَ أَوْ أَيْنَ النُّغَيْرُ؟
