Hadith 1:75
Narrated Abu Bakra (rad):
The Prophet (ﷺ) gave permission for the traveller to perform Mash (wiping) over his leather socks for three days and nights and for a non-traveller for a day and night, if he had put them on in a state of purity. [Reported by Ad-Daraqutni and graded Sahih (sound) by Ibnn Khuzaima].
وَعَنْ أَبِي بَكْرَةَ - رضى الله عنه - عَنْ اَلنَّبِيِّ - صلى الله عليه وسلم -{ أَنَّهُ رَخَّصَ لِلْمُسَافِرِ ثَلَاثَةَ أَيَّامٍ وَلَيَالِيَهُنَّ, وَلِلْمُقِيمِ يَوْمًا وَلَيْلَةً, إِذَا تَطَهَّرَ فَلَبِسَ خُفَّيْهِ: أَنْ يَمْسَحَ عَلَيْهِمَا } أَخْرَجَهُ اَلدَّارَقُطْنِيُّ, وَصَحَّحَهُ اِبْنُ خُزَيْمَة َ (81)
