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. (Using translation from Muslim 2096)  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ فِي غَزْوَةٍ غَزَوْنَاهَا «اسْتَكْثِرُوا مِنَ النِّعَالِ فَإِنَّ الرَّجُلَ لَا يَزَالُ رَاكِبًا مَا انْتَعَلَ»  

The sandals of the Prophet ﷺ had two thongs. (Using translation from Abū Dāʾūd 4134)  

«أَنَّ نَعْلَ رَسُولِ اللهِ ﷺ كَانَ لَهَا قِبَالَانِ»  

[Machine] "The sandals of the Messenger of Allah ﷺ had two straps, the sandals of Abu Bakr had two straps, and the sandals of Umar had two straps."  

«كَانَ لِنَعْلِ رَسُولِ اللهِ ﷺ قِبَالَانِ وَنَعْلِ أَبِي بَكْرٍ قِبَالَانِ وَنَعْلِ عُمَرَ قِبَالَانِ»  

[Machine] Amr ibn Huraith said: I heard the Prophet ﷺ saying, "I saw the Prophet ﷺ praying with two worn-out sandals." Abu Abdur Rahman said, "This is a mistake, the correct thing is what follows."  

سَمِعَ عَمْرَو بْنَ حُرَيْثٍ يَقُولُ رَأَيْتُ النَّبِيَّ ﷺ يُصَلِّي فِي نَعْلَيْنِ مَخْصُوفَتَيْنِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ وَالصَّوَابُ الَّذِي يَلِيهِ  

[Machine] "I saw the Prophet ﷺ praying wearing a pair of worn-out sandals."  

«رَأَيْتُ النَّبِيَّ ﷺ يُصَلِّي فِي نَعْلَيْنِ مَخْصُوفَتَيْنِ»  

[Machine] "I saw the Messenger of Allah ﷺ praying wearing two leather sandals."  

«رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي فِي نَعْلَيْنِ مَخْصُوفَتَيْنِ»
