Saʿd bin Abi Waqqas said, "The Prophet ﷺ passed wet hands over his Khuffs (socks made from thick fabric or leather)." ʿAbdullah bin ʿUmar asked ʿUmar about it. ʿUmar replied in the affirmative and added, "Whenever Saʿd narrates a Hadith from the Prophet, there is no need to ask anyone else about it."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ مَسَحَ عَلَى الْخُفَّيْنِ وَأَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ سَأَلَ عُمَرَ عَنْ ذَلِكَ فَقَالَ نَعَمْ إِذَا حَدَّثَكَ شَيْئًا سَعْدٌ عَنِ النَّبِيِّ ﷺ فَلاَ تَسْأَلْ عَنْهُ غَيْرَهُ وَقَالَ مُوسَى بْنُ عُقْبَةَ أَخْبَرَنِي أَبُو النَّضْرِ أَنَّ أَبَا سَلَمَةَ أَخْبَرَهُ أَنَّ سَعْدًا حَدَّثَهُ فَقَالَ عُمَرُ لِعَبْدِ اللَّهِ نَحْوَهُ  

Once Messenger of Allah ﷺ went out to answer the call of nature and I followed him with a tumbler containing water, and when he finished, I poured water and he performed ablution and passed wet hands over his Khuffs (socks made from thick fabric or leather).  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ خَرَجَ لِحَاجَتِهِ فَاتَّبَعَهُ الْمُغِيرَةُ بِإِدَاوَةٍ فِيهَا مَاءٌ فَصَبَّ عَلَيْهِ حِينَ فَرَغَ مِنْ حَاجَتِهِ فَتَوَضَّأَ وَمَسَحَ عَلَى الْخُفَّيْنِ  

My father said, "I saw the Prophet ﷺ passing wet hands over his Khuffs (socks made from thick fabric or leather)."  

أَخْبَرَهُ أَنَّهُ رَأَى النَّبِيَّ ﷺ يَمْسَحُ عَلَى الْخُفَّيْنِ وَتَابَعَهُ حَرْبُ بْنُ شَدَّادٍ وَأَبَانُ عَنْ يَحْيَى  

My father said, "I saw the Prophet ﷺ passing wet hands over his turban and Khuffs (socks made from thick fabric or leather).  

رَأَيْتُ النَّبِيَّ ﷺ يَمْسَحُ عَلَى عِمَامَتِهِ وَخُفَّيْهِ وَتَابَعَهُ مَعْمَرٌ عَنْ يَحْيَى عَنْ أَبِي سَلَمَةَ عَنْ عَمْرٍو قَالَ رَأَيْتُ النَّبِيَّ ﷺ
