وَعَنْ أَبِي بَكْرَةَ رضى الله عنه عَنْ
اَلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«أَنَّهُ رَخَّصَ لِلْمُسَافِرِ ثَلَاثَةَ أَيَّامٍ وَلَيَالِيَهُنَّ، وَلِلْمُقِيمِ يَوْمًا وَلَيْلَةً، إِذَا تَطَهَّرَ فَلَبِسَ خُفَّيْهِ: أَنْ يَمْسَحَ عَلَيْهِمَا»
The Prophet (sallallahu alayhi wa sallam) 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.
