It was narrated from Abu Hurairah that the Messenger of Allah ﷺ said; “None of you should walk in one sandal or in one leather sock. Let him take them both off or walk in both of them.”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَمْشِي أَحَدُكُمْ فِي نَعْلٍ وَاحِدٍ وَلاَ خُفٍّ وَاحِدٍ لِيَخْلَعْهُمَا جَمِيعًا أَوْ لِيَمْشِ فِيهِمَا جَمِيعًا
