"The Prophet ﷺ granted us a dispensation when traveling, allowing us not to take off our Khuffs for three days and three nights."  

رَخَّصَ لَنَا النَّبِيُّ ﷺ إِذَا كُنَّا مُسَافِرِينَ أَنْ لاَ نَنْزِعَ خِفَافَنَا ثَلاَثَةَ أَيَّامٍ وَلَيَالِيَهُنَّ  

"I asked Safwan bin 'Assal about wiping over the Khuffs, and he said: 'The Messenger of Allah ﷺ used to tell us, when we were travelling, to wipe over our Khuffs and not take them off for three nights in the event of defecating, urinating or sleeping; only in the case of Janabah.'"  

كَانَ رَسُولُ اللَّهِ ﷺ يَأْمُرُنَا إِذَا كُنَّا مُسَافِرِينَ أَنْ نَمْسَحَ عَلَى خِفَافِنَا وَلاَ نَنْزِعَهَا ثَلاَثَةَ أَيَّامٍ مِنْ غَائِطٍ وَبَوْلٍ وَنَوْمٍ إِلاَّ مِنْ جَنَابَةٍ
