مُسَدَّدٌ ، قَالَ : حَدَّثَنَا
أَبُو عَوَانَةَ ، عَنْ
أَبِي بِشْرٍ ، عَنْ
يُوسُفَ بْنِ مَاهَكَ ، عَنْ
عَبْدِ اللَّهِ بْنِ عَمْرٍو ، قَالَ : " تَخَلَّفَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ سَافَرْنَاهُ ، فَأَدْرَكَنَا وَقَدْ أَرْهَقْنَا الصَّلَاةَ صَلَاةَ الْعَصْرِ وَنَحْنُ نَتَوَضَّأُ فَجَعَلْنَا نَمْسَحُ عَلَى أَرْجُلِنَا ، فَنَادَى بِأَعْلَى صَوْتِهِ : وَيْلٌ لِلْأَعْقَابِ مِنَ النَّارِ مَرَّتَيْنِ أَوْ ثَلَاثًا " .
Narrated `Abdullah bin `Amr: Once Allah's Apostle remained behind us in a journey. He joined us while we were performing ablution for the `Asr prayer which was over-due. We were just passing wet hands over our feet (not washing them properly) so the Prophet addressed us in a loud voice and said twice or thrice, "Save your heels from the fire."
