Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "Do not wear one sandal. Wear both of them or go with both feet bare."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَمْشِيَنَّ أَحَدُكُمْ فِي نَعْلٍ وَاحِدَةٍ لِيُنْعَلْهُمَا جَمِيعًا أَوْ لِيُحْفِهِمَا جَمِيعًا
