1. Purification
١۔ كتاب الطهارة وسننها
"I asked 'Aishah about wiping over the leather socks and she said: 'Go to 'Ali and ask him, for he knows more about that than I do.' So I went to 'Ali and asked him about wiping. He said: 'The Messenger of Allah used to tell us that the resident could wipe for one day and one night, and the traveler could do so for three days.'"
فَقَالَتِ ائْتِ عَلِيًّا فَسَلْهُ فَإِنَّهُ أَعْلَمُ بِذَلِكَ مِنِّي فَأَتَيْتُ عَلِيًّا فَسَأَلْتُهُ عَنِ الْمَسْحِ فَقَالَ كَانَ رَسُولُ اللَّهِ ﷺ يَأْمُرُنَا أَنْ نَمْسَحَ لِلْمُقِيمِ يَوْمًا وَلَيْلَةً وَلِلْمُسَافِرِ ثَلاَثَةَ أَيَّامٍ
"The Messenger of Allah set a time limit for the traveler of three days, and if the questioner had persisted in asking, he would have made it five (days)."
جَعَلَ رَسُولُ اللَّهِ ﷺ لِلْمُسَافِرِ ثَلاَثًا وَلَوْ مَضَى السَّائِلُ عَلَى مَسْأَلَتِهِ لَجَعَلَهَا خَمْسًا
The Prophet said: "Three days." I think he said, "And three nights during which the traveler may wipe over his leather socks."
عَنِ النَّبِيِّ ﷺ قَالَ ثَلاَثَةُ أَيَّامٍ أَحْسِبُهُ قَالَ وَلَيَالِيهِنَّ لِلْمُسَافِرِ فِي الْمَسْحِ عَلَى الْخُفَّيْنِ
"They said: 'O Messenger of Allah! What about the purification of the leather socks?' He said: 'For the traveler it is three days and nights, and for the resident it is one day and one night.'"
قَالُوا يَا رَسُولَ اللَّهِ مَا الطُّهُورُ عَلَى الْخُفَّيْنِ قَالَ لِلْمُسَافِرِ ثَلاَثَةُ أَيَّامٍ وَلَيَالِيهِنَّ وَلِلْمُقِيمِ يَوْمٌ وَلَيْلَةٌ
The Prophet granted a concession to travelers: "If a traveler performed ablution and put on leather socks, then he performed a fresh ablution, he could wipe over the leather socks for three days and nights; the resident could do so for one day and one night."
عَنِ النَّبِيِّ ﷺ أَنَّهُ رَخَّصَ لِلْمُسَافِرِ إِذَا تَوَضَّأَ وَلَبِسَ خُفَّيْهِ ثُمَّ أَحْدَثَ وُضُوءًا أَنْ يَمْسَحَ ثَلاَثَةَ أَيَّامٍ وَلَيَالِيَهُنَّ وَلِلْمُقِيمِ يَوْمًا وَلَيْلَةً
