١٠ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ عَلِيِّ بْنِ إِسْمَاعِيلَ عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ جَعْفَرِ بْنِ سُلَيْمَانَ عَمِّهِ قَالَ سَأَلْتُ أَبَا الْحَسَنِ مُوسَى (عَلَيْهِ الْسَّلام) قُلْتُ جُعِلْتُ فِدَاكَ يَكُونُ خُفُّ الرَّجُلِ مُخَرَّقاً فَيُدْخِلُ يَدَهُ فَيَمْسَحُ ظَهْرَ قَدَمِهِ أَ يُجْزِئُهُ ذَلِكَ قَالَ نَعَمْ.
10. Muhammad ibn Yahya has narrated from Ali ibn ’Isma‘il from Ali ibn al-Nu‘man from al-Qasim ibn Muhammad from Ja‘far ibn Sulayman, his uncle who has said the following: “I once asked abu al-Hassan, Musa , saying, ‘I pray to Allah to keep my soul in service for your cause, if the back of one’s slipper is torn and he pushes his hand through the torn portion to wipe the back of his feet, is this acceptable?’ He (the Imam) said, ‘Yes, it is sufficient.’”
