Chapter 134 | The Saltwort and Cyperus
مُحَمَّدُ بْنُ يَحْيَى عَنْ عَلِيِّ بْنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَحْمَدَ بْنِ الْحُسَيْنِ بْنِ عُمَرَ عَنْ عَمِّهِ مُحَمَّدِ بْنِ عُمَرَ عَنْ رَجُلٍ عَنْ أَبِي الْحَسَنِ الْأَوَّلِ ( عليه السلام ) قَالَ مَنِ اسْتَنْجَى بِالسُّعْدِ بَعْدَ الْغَائِطِ وَ غَسَلَ بِهِ فَمَهُ بَعْدَ الطَّعَامِ لَمْ تُصِبْهُ عِلَّةٌ فِي فَمِهِ وَ لَمْ يَخَفْ شَيْئاً مِنْ أَرْيَاحِ الْبَوَاسِيرِ .
