Hadith 60
حَدَّثَنَا أَبُو النُّعْمَانِ عَارِمُ بْنُ الْفَضْلِ ، قَالَ : حَدَّثَنَا أَبُو عَوَانَةَ ، عَنْ أَبِي بِشْرٍ ، عَنْ يُوسُفَ بْنِ مَاهَكَ ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو ، قَالَ : تَخَلَّفَ عَنَّا النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفْرَةٍ سَافَرْنَاهَا ، فَأَدْرَكَنَا وَقَدْ أَرْهَقَتْنَا الصَّلَاةُ وَنَحْنُ نَتَوَضَّأُ ، فَجَعَلْنَا نَمْسَحُ عَلَى أَرْجُلِنَا ، فَنَادَى بِأَعْلَى صَوْتِهِ : " وَيْلٌ لِلْأَعْقَابِ مِنَ النَّارِ مَرَّتَيْنِ أَوْ ثَلَاثًا " .
Narrated `Abdullah bin `Amr: Once the Prophet remained behind us in a journey. He joined us while we were performing ablution for the prayer which was over-due. We were just passing wet hands over our feet (and not washing them properly) so the Prophet addressed us in a loud voice and said twice or thrice: "Save your heels from the fire."
