[Machine] I heard my father, Abd al-Rahman al-Hubuli, say: I saw the Messenger of Allah ﷺ massaging between his toes with his pinky finger.  

سَمِعْتُ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيَّ يَقُولُ رَأَيْتُ رَسُولَ اللهِ ﷺ يُدَلِّكُ بِخِنْصَرِهِ مَا بَيْنَ أَصَابِعِ رِجْلَيْهِ  

[Machine] I left him until the people calmed down, and then I said to him, "O Abu Abdullah, I heard you giving a fatwa regarding removing the calluses from the fingers of the feet, claiming that it is not necessary for people, but it is a sunnah for us." He asked, "What is the evidence for that?" I said, "Al-Layth ibn Sa'd, Ibn Lahi'ah, and 'Amr ibn al-Harith narrated from Yazid ibn 'Amr al-Ma'afiri, who narrated from Abu 'Abd al-Rahman al-Hubuli, who narrated from al-Mustawrid ibn Shaddad al-Qurashi, who said, 'I saw the Messenger of Allah ﷺ massaging the space between his toes with his little finger. He said, 'This is a good hadith, and I have never heard of it before except at this hour.' Then, I heard him being asked about this later, and he ordered the removal of the calluses. My paternal uncle said, 'I have never seen anyone perform ablution without the line under the thumb on the foot surrounding them. For people touch their thumbs during ablution, and whoever overlooks that is safe.'"  

فَتَرَكْتُهُ حَتَّى خَفَّ النَّاسُ فَقُلْتُ لَهُ يَا أَبَا عَبْدَ اللهِ سَمِعْتُكَ تُفْتِي فِي مَسْأَلَةِ تَخْلِيلِ أَصَابِعِ الرِّجْلَيْنِ زَعَمْتَ أَنْ لَيْسَ ذَلِكَ عَلَى النَّاسِ وَعِنْدَنَا فِي ذَلِكَ سُنَّةٌ فَقَالَ وَمَا هِيَ؟ فَقُلْتُ ثنا اللَّيْثُ بْنُ سَعْدٍ وَابْنُ لَهِيعَةَ وَعَمْرُو بْنُ الْحَارِثِ عَنْ يَزِيدَ بْنِ عَمْرٍو الْمَعَافِرِيِّ عَنْ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيِّ عَنِ الْمُسْتَوْرِدِ بْنِ شَدَّادٍ الْقُرَشِيِّ قَالَ رَأَيْتُ رَسُولَ اللهِ ﷺ يُدَلِّكُ بِخِنْصَرِهِ مَا بَيْنَ أَصَابِعِ رِجْلَيْهِ فَقَالَ إِنَّ هَذَا حَدِيثٌ حَسَنٌ وَمَا سَمِعْتُ بِهِ قَطُّ إِلَّا السَّاعَةَ ثُمَّ سَمِعْتُهُ يُسْأَلُ بَعْدَ ذَلِكَ فَأَمَرَ بِتَخْلِيلِ الْأَصَابِعِ قَالَ عَمِّي مَا أَقَلَّ مَنْ يَتَوَضَّأُ إِلَّا وَيُحِيطُهُ الْخَطُّ الَّذِي تَحْتَ الْإِبْهَامِ فِي الرِّجْلِ فَإِنَّ النَّاسَ يُثْنُونَ إِبْهَامَهُمْ عِنْدَ الْوُضُوءِ وَمَنْ تَفَقَّدَ ذَلِكَ سَلِمَ
