مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ قَالَ سَأَلْتُ أَبَا الْحَسَنِ ( صلوات الله عليه ) عَنِ الْفِرَاشِ الْحَرِيرِ وَ مِثْلِهِ مِنَ الدِّيبَاجِ وَ الْمُصَلَّى الْحَرِيرِ وَ مِثْلِهِ مِنَ الدِّيبَاجِ هَلْ يَصْلُحُ لِلرَّجُلِ النَّوْمُ عَلَيْهِ وَ التُّكَأَةُ وَ الصَّلَاةُ فَقَالَ يَفْرِشُهُ وَ يَقُومُ عَلَيْهِ وَ لَا يَسْجُدُ عَلَيْهِ .
8. Muhammad ibn Yahya has narrated from al-‘Amrakiy ibn Ali from Ali ibn Ja‘far who has said the following: “I once asked abu al-Hassan , about silk furnishings and similarly about brocaded items, prayer rugs of silk and of brocaded ones; if it is proper for a man to sleep on it, perform Salat (prayer) or lean against it. He (the Imam) said, ‘He can spread it and stand on it but he cannot perform Sajdah (prostration) on it.’”
