Sahih Muslim 2096
Jabir reported:
I heard Allah's Apostle (ﷺ) saying during an expedition in which we also participated: Make a general practice of wearing sandals, for a man is riding as it were when he wears sandals.
حَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، عَنْ أَبِي الزُّبَيْرِ، عَنْ 
جَابِرٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ فِي غَزْوَةٍ غَزَوْنَاهَا ‏
"‏ اسْتَكْثِرُوا مِنَ
النِّعَالِ فَإِنَّ الرَّجُلَ لاَ يَزَالُ رَاكِبًا مَا انْتَعَلَ ‏"‏ ‏.‏
