The Prophet ﷺ saw a person offering prayer, and on the back of his foot a small part equal to the space of a dirham remained unwashed; the water did not reach it. The Prophet ﷺ commanded him to repeat the ablution and prayer. (Using translation from Abū Dāʾūd 175)   

البيهقي:٣٩٢أَخْبَرَنَا أَبُو عَلِيٍّ الْحُسَيْنُ بْنُ مُحَمَّدٍ الرُّوذْبَارِيُّ أنا أَبُو بَكْرٍ مُحَمَّدُ بْنُ بَكْرٍ ثنا أَبُو دَاودَ نا حَيْوَةُ بْنُ شُرَيْحٍ ثنا بَقِيَّةُ عَنْ بَحِيْرٍ يَعْنِي ابْنَ سَعِيدٍ عَنْ خَالِدٍ يَعْنِي ابْنَ مَعْدَانَ

عَنْ بَعْضِ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ رَأَى رَجُلًا يُصَلِّي وَفِي ظَهْرِ قَدَمِهِ لُمْعَةٌ قَدْرُ الدِّرْهَمِ لَمْ يُصِبْهَا الْمَاءُ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يُعِيدَ الْوُضُوءَ وَالصَّلَاةَ كَذَا فِي هَذَا الْحَدِيثِ وَهُوَ مُرْسَلٌ وَرُوِيَ فِي حَدِيثٍ مَوْصُولٍ
