(19) بَاب اسْتِحْبَابِ لُبْسِ النَّعْلِ فِي الْيُمْنَى أَوَّلًا وَالْخَلْعِ مِنْ الْيُسْرَى أَوَّلًا وَكَرَاهَةِ الْمَشْيِ فِي نَعْلٍ وَاحِدَةٍ
Abu Huraire reported Allah's Messenger (ﷺ) as saying:
When one of you puts on sandals, he should first put in the right foot, and when he takes off he should take off the left one first, or he should put them on together or take them off together.
