(حديث مرفوع) حَدَّثَنَا
إِبْرَاهِيمُ بْنُ أَبِي الْعَبَّاسِ ، حَدَّثَنَا
بَقِيَّةُ ، حَدَّثَنَا
بَحِيرُ بْنُ سَعْدٍ ، عَنْ
خَالِدِ بْنِ مَعْدَانَ ، عَنْ
بَعْضِ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " رَأَى رَجُلًا يُصَلِّي ، وَفِي ظَهْرِ قَدَمِهِ لُمْعَةٌ قَدْرُ الدِّرْهَمِ ، لَمْ يُصِبْهَا الْمَاءُ ، فَأَمَرَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يُعِيدَ الْوُضُوءَ " .
It is narrated from a companion that the Prophet (peace be upon him) saw a man who was praying, and on the back of his foot there was a spot about the size of a dirham where water had not reached. The Prophet (peace be upon him) ordered him to repeat his ablution.
