ahmad-zuhd:1517ʿAbdullāh > Rawḥ b. ʿAbd al-Muʾmin Abū al-Ḥasan al-Muqrī > Khālid b. Shawdhab

[Machine] I saw al-Sinji lying down with a woolen cloak on him. Al-Hasan took his cloak and said, "O son of Farqad, two or three times have passed where piety is not in this garment; rather, piety is what is settled in the heart and confirmed by actions and deeds."  

الزهد لأحمد:١٥١٧حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي رَوْحُ بْنُ عَبْدِ الْمُؤْمِنِ أَبُو الْحَسَنِ الْمُقْرِي حَدَّثَنَا خَالِدُ بْنُ شَوْذَبٍ قَالَ

رَأَيْتُ فَرْقَدًا السِّنْجِيَّ وَعَلَيْهِ جُبَّةٌ صُوفٌ فَأَخَذَ الْحَسَنُ بِجُبَّتِهِ ثُمَّ قَالَ يَا ابْنَ فَرْقَدٍ مَرَّتَيْنِ أَوْ ثَلَاثَةً «إِنَّ التَّقْوَى لَيْسَ فِي هَذَا الْكِسَاءِ إِنَّمَا التَّقْوَى مَا وَقَرَ فِي الْقَلْبِ وَصَدَّقَهُ الْعَمَلُ وَالْفِعْلُ»
