سَهْلُ بْنُ زِيَادٍ عَنْ مُحَمَّدِ بْنِ عِيسَى أَوْ غَيْرِهِ عَنْ أَبِي دَاوُدَ الْمُسْتَرِقِّ قَالَ مَنْ ضُرِبَ فِي بَيْتِهِ بَرْبَطٌ أَرْبَعِينَ يَوْماً سَلَّطَ اللَّهُ عَلَيْهِ شَيْطَاناً يُقَالُ لَهُ الْقَفَنْدَرُ فَلَا يُبْقِي عُضْواً مِنْ أَعْضَائِهِ إِلَّا قَعَدَ عَلَيْهِ فَإِذَا كَانَ كَذَلِكَ نُزِعَ مِنْهُ الْحَيَاءُ وَ لَمْ يُبَالِ مَا قَالَ وَ لَا مَا قِيلَ فِيهِ .
17. Sahl ibn Ziyad has narrated from Muhammad ibn ‘Isa or others from abu Dawud al-Mustariq who has said the following: “He (the Imam) , has said, ‘If barbat is played in one’s house for forty days Allah gives its control to a Satan called al-Qafandar who sits on every part of the body of the owner of the house. When this happens bashfulness (the sense to feel ashamed of one’s indecent acts) is taken away from him and he does not mind whatever he says or is said about him.’”
