Sunan Ibn Majah, Book 5, Hadith 1499 (In-Book) ⓘ
It was narrated that Abu Hurairah said: “The Messenger of Allah said: ‘Keep your shoes on your feet. If you take them off then place them between your two feet; do not place them to your right, or to the right of your companions, or behind you, for they may annoy whoever is behind you.’”
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ بْنِ حَبِيبٍ، وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ، قَالاَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ الْمُحَارِبِيُّ، عَنْ عَبْدِ اللَّهِ بْنِ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " أَلْزِمْ نَعْلَيْكَ قَدَمَيْكَ فَإِنْ خَلَعْتَهُمَا فَاجْعَلْهُمَا بَيْنَ رِجْلَيْكَ وَلاَ تَجْعَلْهُمَا عَنْ يَمِينِكَ وَلاَ عَنْ يَمِينِ صَاحِبِكَ وَلاَ وَرَاءَكَ فَتُؤْذِيَ مَنْ خَلْفَكَ " .
