أَبُو عَلِيٍّ الْأَشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنِ ابْنِ فَضَّالٍ عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ بْنِ كَثِيرٍ الْخَزَّازِ عَنْ أَبِيهِ قَالَ رَأَيْتُ أَبَا عَبْدِ اللَّهِ ( عليه السلام ) وَ عَلَيْهِ قَمِيصٌ غَلِيظٌ خَشِنٌ تَحْتَ ثِيَابِهِ وَ فَوْقَهَا جُبَّةُ صُوفٍ وَ فَوْقَهَا قَمِيصٌ غَلِيظٌ فَمَسِسْتُهَا فَقُلْتُ جُعِلْتُ فِدَاكَ إِنَّ النَّاسَ يَكْرَهُونَ لِبَاسَ الصُّوفِ فَقَالَ كَلَّا كَانَ أَبِي مُحَمَّدُ بْنُ عَلِيٍّ ( عليه السلام ) يَلْبَسُهَا وَ كَانَ عَلِيُّ بْنُ الْحُسَيْنِ ( عليه السلام ) يَلْبَسُهَا وَ كَانُوا ( عليهم السلام ) يَلْبَسُونَ أَغْلَظَ ثِيَابِهِمْ إِذَا قَامُوا إِلَى الصَّلَاةِ وَ نَحْنُ نَفْعَلُ ذَلِكَ .
4. Abu Ali al-Ash‘ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from ibn Faddal from Muhammad ibn al-Hassan ibn Kathir al- Khazzaz from his father who has said the following: “I saw abu ‘Abd Allah , wearing a shirt of rough texture underneath his clothes, over which was a woolen gown over which was a thick shirt and I felt it, and said, ‘I pray to Allah to keep my soul in service for your cause, people dislike wearing wool.’ He (the Imam) said, ‘Not so, my father, Muhammad ibn Ali , would wear it as well as Ali ibn al-Husayn , did. They, ‘Alayhim al-Salam, wore their clothes of the roughest texture in their Salat (prayer) and we also do so.’”
