9ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ رِفَاعَةَ قَالَ حَدَّثَنِي مَنْ سَمِعَ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الرَّجُلِ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ مُتَّزِراً بِهِ قَالَ لاَ بَأْسَ بِهِ إِذَا رَفَعَهُ إِلَى الثُّنْدُوَتَيْنِ.
9. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Rifa‘ah who has said the following: “The person who had heard abu ‘Abd Allah (a.s.), narrated to me about a man who performs Salah (prayer) in one piece of cloth using it as a loincloth. He (the Imam) said, ‘There is no offense in it if he raises it up to his chest.’”
