مَا رُئِيَ رَسُولُ اللَّهِ ﷺ يَأْكُلُ مُتَّكِئًا قَطُّ وَلاَ يَطَأُ عَقِبَيْهِ رَجُلاَنِ قَالَ أَبُو الْحَسَنِ وَحَدَّثَنَا خَازِمُ بْنُ يَحْيَى حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْحَجَّاجِ السَّامِيُّ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ قَالَ أَبُو الْحَسَنِ وَحَدَّثَنَا إِبْرَاهِيمُ بْنُ نَصْرٍ الْهَمْدَانِيُّ صَاحِبُ الْقَفِيزِ حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ  

"The Prophet walked on a very hot day towards Baqi' Al-Gharqad (graveyard of Al-Madinah), and the people were walking behind him. When he heard the sound of their shoes, it affected his soul so he sat down until he made them go ahead of him, lest that make him feel too proud."  

مَرَّ النَّبِيُّ ﷺ فِي يَوْمٍ شَدِيدِ الْحَرِّ نَحْوَ بَقِيعِ الْغَرْقَدِ وَكَانَ النَّاسُ يَمْشُونَ خَلْفَهُ فَلَمَّا سَمِعَ صَوْتَ النِّعَالِ وَقَرَ ذَلِكَ فِي نَفْسِهِ فَجَلَسَ حَتَّى قَدَّمَهُمْ أَمَامَهُ لِئَلاَّ يَقَعَ فِي نَفْسِهِ شَىْءٌ مِنَ الْكِبْرِ  

"When the Prophet walked, his Companions would walk in front of him, and he would leave his back for the angels."  

عَنْ نُبَيْحٍ الْعَنَزِيِّ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ قَالَ كَانَ النَّبِيُّ ﷺ إِذَا مَشَى مَشَى أَصْحَابُهُ أَمَامَهُ وَتَرَكُوا ظَهْرَهُ لِلْمَلاَئِكَةِ
