[Machine] A man came to the Prophet ﷺ having performed ablution, but he left a small area on his foot unwashed. So the Messenger of Allah ﷺ told him to go back and perfect his ablution. Abu Dawood said: "This hadith is not well-known and it has not been narrated from Jarir ibn Hazim except by Ibn Wahb, and with this chain it means the same as the hadith of Qatadah, and this (narration) is Mursal." Abu Dawood said that Musa ibn Ismail narrated to him from Hammad, from Yunus and Humaid, from Al Hasan, from the Prophet ﷺ with a similar meaning to the hadith of Qatadah, and this is a Mursal hadith. Abu Dawood added.  

أَنَّ رَجُلًا جَاءَ إِلَى النَّبِيِّ ﷺ قَدْ تَوَضَّأَ وَتَرَكَ عَلَى قَدَمِهِ مِثْلَ مَوْضِعِ الظُّفُرِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ ارْجِعْ فَأَحْسِنْ وُضُوءَكَ قَالَ أَبُو دَاودَ وَلَيْسَ هَذَا الْحَدِيثُ بِمَعْرُوفٍ وَلَمْ يَرْوِهِ عَنْ جَرِيرِ بْنِ حَازِمٍ إِلَّا ابْنُ وَهْبٍ يَعْنِي بِهَذَا الْإِسْنَادِ قَالَ أَبُو دَاودَ ثنا مُوسَى بْنُ إِسْمَاعِيلَ ثنا حَمَّادٌ ثنا يُونُسُ وَحُمَيْدٌ عَنِ الْحَسَنِ عَنِ النَّبِيِّ ﷺ بِمَعْنَى حَدِيثِ قَتَادَةَ وَهَذَا مُرْسَلٌ قَالَ أَبُو دَاودَ
