The Prophet ﷺ passed by a boy who was skinning a goat. The Messenger of Allah ﷺ said: Give it up until I show you. He (the Prophet) inserted his hand between the skin and the flesh until it reached the armpit. He then went away and led the people in prayer and he did not perform ablution. The version of Amr added that he did not touch water. Abu Dawud said: This tradition has been narrated though another chain of transmitters, making no mention of Abu Sa'id.  

أَنَّ النَّبِيَّ ﷺ مَرَّ بِغُلاَمٍ وَهُوَ يَسْلُخُ شَاةً فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ تَنَحَّ حَتَّى أُرِيَكَ فَأَدْخَلَ يَدَهُ بَيْنَ الْجِلْدِ وَاللَّحْمِ فَدَحَسَ بِهَا حَتَّى تَوَارَتْ إِلَى الإِبْطِ ثُمَّ مَضَى فَصَلَّى لِلنَّاسِ وَلَمْ يَتَوَضَّأْ  

“Step aside and I will show you how.” The Messenger of Allah ﷺ put his hand between the skin and the flesh, and thrust his arm in until it disappeared up to the armpit, and said: “O boy, this is how you skin it.” Then he went and led the people in prayer and did not perform Wudu’. (Using translation from Ibn Mājah 3179)   

أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ بِغُلَامٍ يَسْلُخُ شَاةً فَقَالَ لَهُ «تَنَحَّ حَتَّى أُرِيَكَ فَإِنِّي لَا أَرَاكَ تُحْسِنُ تَسْلُخُ» قَالَ فَأَدْخَلَ رَسُولُ اللَّهِ ﷺ يَدَهُ بَيْنَ الْجِلْدِ وَاللَّحْمِ فَدَحَسَ بِهَا حَتَّى تَوَارَتْ إِلَى الْإِبْطِ ثُمَّ قَالَ ﷺ «هَكَذَا يَا غُلَامُ فَاسْلُخْ» ثُمَّ انْطَلَقَ فَصَلَّى وَلَمْ يَتَوَضَّأْ وَلَمْ يَمَسَّ مَاءً  

[Machine] The Prophet ﷺ once passed by a boy who was skinning a sheep. The Messenger of Allah ﷺ said to him, "Stop for a moment so that I may show you something." He then placed his hand between the skin and the meat and crushed it until it disappeared beneath his armpit. He then left and performed prayer without performing ablution. Abu Dawood added that 'Amr mentioned in his hadith that the Prophet ﷺ did not touch water. Hilal ibn Maymoon al-Ramli reported from Abu Dawood, and 'Abdul Wahid ibn Ziyad and Abu Muawiyah reported from Hilal, who reported from 'Ata that the Prophet ﷺ sent him saying something on his behalf to Abu Sa'eed.  

أَنَّ النَّبِيَّ ﷺ مَرَّ بِغُلَامٍ يَسْلُخُ شَاةً فَقَالَ لَهُ رَسُولُ اللهِ ﷺ تَنَحَّ حَتَّى أُرِيَكَ فَأَدْخَلَ يَدَهُ بَيْنَ الْجِلْدِ وَاللَّحْمِ فَدَحَسَ بِهَا حَتَّى تَوَارَتْ إِلَى الْإِبْطِ ثُمَّ مَضَى فَصَلَّى بِالنَّاسِ وَلَمْ يَتَوَضَّأْ قَالَ أَبُو دَاوُدَ زَادَ عَمْرٌو فِي حَدِيثِهِ يَعْنِي لَمْ يَمَسَّ مَاءً وَقَالَ عَنْ هِلَالِ بْنِ مَيْمُونٍ الرَّمْلِيِّ قَالَ أَبُو دَاوُدَ وَرَوَاهُ عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ وَأَبُو مُعَاوِيَةَ عَنْ هِلَالٍ عَنْ عَطَاءٍ عَنِ النَّبِيِّ ﷺ مُرْسَلًا لَمْ يَذْكُرْ أَبَا سَعِيدٍ  

"عَن أبِى سَعِيدٍ قَالَ: مَرَّ النَّبِىُّ ﷺ بِغُلَام يَسْلُخُ شَاةً، فَقَالَ لَهُ: تَنَحَّ حَتَّى أريَكَ فَإنِّى لَا أراكَ تُحْسنُ تَسْلُخُ، فَأدْخَلَ رَسُولُ الله ﷺ يَدَهُ بَيْنَ الجْلدِ وَاللَّحْم فدحس (*) بِهَا حَتَّى تَوَارَتْ إِلَى الإبِطِ وَقَالَ: هَكَذَا يَا غُلَامُ فَاسْلُخْ ثُمَّ انْطَلَقَ فَصَلَّى بِالنَّاسِ وَلَمْ يَتَوَضأ - يَعْنِي لَمْ يَمسَّ مَاءً".
