Sunan an-Nasa'i 129
It was narrated that Shuraih bin Hani' said:
"I asked 'Aishah about wiping over the Khuffs and she said: 'Go to 'Ali, for he knows more about that than I do.' So I went to 'Ali and asked him about wiping (over the Khuffs) and he said: 'The Messenger of Allah (ﷺ) used to tell us to wipe (over the Khuffs) for one day and one night for the resident, and three for the traveler.'"
أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، عَنْ أَبِي مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنِ الْحَكَمِ، عَنِ الْقَاسِمِ بْنِ مُخَيْمِرَةَ، عَنْ شُرَيْحِ بْنِ هَانِئٍ، قَالَ سَأَلْتُ عَائِشَةَ - رضى الله عنها - عَنِ الْمَسْحِ عَلَى الْخُفَّيْنِ فَقَالَتِ ائْتِ عَلِيًّا فَإِنَّهُ أَعْلَمُ بِذَلِكَ مِنِّي ‏.‏ فَأَتَيْتُ عَلِيًّا فَسَأَلْتُهُ عَنِ الْمَسْحِ فَقَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَأْمُرُنَا أَنْ يَمْسَحَ الْمُقِيمُ يَوْمًا وَلَيْلَةً وَالْمُسَافِرُ ثَلاَثًا ‏.‏
