Messenger of Allah ﷺ said, "None of you should walk, wearing one shoe only; he should either put on both shoes or put on no shoes whatsoever."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَمْشِي أَحَدُكُمْ فِي نَعْلٍ وَاحِدَةٍ لِيُحْفِهِمَا جَمِيعًا أَوْ لِيَنْعَلْهُمَا جَمِيعًا  

"I saw Abu Hurairah clap his hand to his forehead and say: 'O people of Al-'Iraq, you claim that I tell lies about the Messenger of Allah [SAW]. I bear witness that I heard the Messenger of Allah [SAW] say: If the strap of the sandal of one of you breaks, let him not walk in the other until he fixes it.'"  

رَأَيْتُ أَبَا هُرَيْرَةَ يَضْرِبُ بِيَدِهِ عَلَى جَبْهَتِهِ يَقُولُ يَا أَهْلَ الْعِرَاقِ تَزْعُمُونَ أَنِّي أَكْذِبُ عَلَى رَسُولِ اللَّهِ ﷺ أَشْهَدُ لَسَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا انْقَطَعَ شِسْعُ نَعْلِ أَحَدِكُمْ فَلاَ يَمْشِ فِي الأُخْرَى حَتَّى يُصْلِحَهَا  

The Prophet [SAW] said: "If the strap of the sandal of one of you breaks, let him not walk in one sandal until he fixes it."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا انْقَطَعَ شِسْعُ نَعْلِ أَحَدِكُمْ فَلاَ يَمْشِ فِي نَعْلٍ وَاحِدَةٍ حَتَّى يُصْلِحَهَا  

The Messenger of Allah ﷺ forbade that a man should put on sandals while standing.  

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَنْتَعِلَ الرَّجُلُ قَائِمًا
