[Machine] The Messenger of Allah ﷺ performed ablution and wiped over his slippers while they were cut. Abu Bakr ibn Fuhrk informed us that Abdullah ibn Ja'far narrated to us that Yunus ibn Habib narrated to us that Abu Dawud al-Tayalisi narrated to us that Hammad ibn Salamah mentioned it. And this chain of narration is not strong, but it indicates what the first hadith suggests, which is that it refers to washing the two feet while wearing slippers.  

أَنَّ رَسُولَ اللهِ ﷺ تَوَضَّأَ وَمَسَحَ عَلَى نَعْلَيْهِ وَهُو مُنْقَطِعٌ أَخْبَرَنَاهُ أَبُو بَكْرِ بْنُ فُورَكٍ أنا عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يُونُسُ بْنُ حَبِيبٍ ثنا أَبُو دَاوُدَ الطَّيَالِسِيُّ ثنا حَمَّادُ بْنُ سَلَمَةَ فَذَكَرَهُ وَهَذَا الْإِسْنَادُ غَيْرُ قَوِيٍّ وَهُوَ يَحْتَمِلُ مَا احْتَمَلَ الْحَدِيثَ الْأَوْلَ وَالَّذِي يَدُلُّ عَلَى أَنَّ الْمُرَادَ بِهِ غَسْلُ الرِّجْلَيْنِ فِي النَّعْلَيْنِ
