[Machine] I saw a peacock raise its hands to its shoulders when saying the takbeer, when bowing, and when raising its head from the bow. So I asked a man from its companions, and he said that he learned it from Ibn Umar, from the Prophet ﷺ . Abu Abdullah al-Hafiz said, "Both hadiths are preserved from Ibn Umar, from Umar, from the Prophet ﷺ . Ibn Umar saw the Prophet ﷺ do it, so he did it, and he saw his father do it, so he did it, and he narrated it from the Prophet ﷺ ."  

رَأَيْتُ طَاوُسًا كَبَّرَ فَرَفَعَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ عِنْدَ التَّكْبِيرِ وَعِنْدَ رُكُوعِهِ وَعِنْدَ رِفْعِهِ رَأْسَهُ مِنَ الرُّكُوعِ فَسَأَلْتُ رَجُلًا مِنْ أَصْحَابِهِ فَقَالَ إِنَّهُ يُحَدِّثُ بِهِ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ قَالَ أَبُو عَبْدِ اللهِ الْحَافِظُ فَالْحَدِيثَانِ كِلَاهُمَا مَحْفُوظَانِ عَنِ ابْنِ عُمَرَ عَنْ عُمَرَ عَنِ النَّبِيِّ ﷺ وَابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ فَإِنَّ ابْنَ عُمَرَ رَأَى النَّبِيَّ ﷺ فَعَلَهُ وَرَأَى أَبَاهُ فَعَلَهُ وَرَوَاهُ عَنِ النَّبِيِّ ﷺ
