Sunan Ibn Majah, Book 1, Hadith 606 (In-Book) ⓘ
It was narrated that Abu Muslim, the freed slave of Zaid bin Suhan, said: "I was with Salman, and he saw a man removing his leather socks for ablution. Salman said to him" 'Wipe over your leather socks and your head cover, and your forehead, for I saw the Messenger of Allah wiping over his leather socks and head cover.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يُونُسُ بْنُ مُحَمَّدٍ، عَنْ دَاوُدَ بْنِ أَبِي الْفُرَاتِ، عَنْ مُحَمَّدِ بْنِ زَيْدٍ، عَنْ أَبِي شُرَيْحٍ، عَنْ أَبِي مُسْلِمٍ، مَوْلَى زَيْدِ بْنِ صُوحَانَ قَالَ كُنْتُ مَعَ سَلْمَانَ فَرَأَى رَجُلاً يَنْزِعُ خُفَّيْهِ لِلْوُضُوءِ فَقَالَ لَهُ سَلْمَانُ امْسَحْ عَلَى خُفَّيْكَ وَعَلَى خِمَارِكَ وَبِنَاصِيَتِكَ فَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَمْسَحُ عَلَى الْخُفَّيْنِ وَالْخِمَارِ .
