١ حَدَّثَنِي مُحَمَّدُ بْنُ يَعْقُوبَ وَ جَمَاعَةُ مَشَايِخِي ره عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ أَبِي يَحْيَى الْوَاسِطِيِّ عَنْ رَجُلٍ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ الطِّينُ كُلُّهُ حَرَامٌ كَلَحْمِ الْخِنْزِيرِ وَ مَنْ أَكَلَهُ ثُمَّ مَاتَ مِنْهُ لَمْ أُصَلِّ عَلَيْهِ إِلَّا طِينَ قَبْرِ الْحُسَيْنِ (ع) فَإِنَّ فِيهِ شِفَاءً مِنْ كُلِّ دَاءٍ وَ مَنْ أَكَلَهُ بِشَهْوَةٍ لَمْ يَكُنْ فِيهِ شِفَاءٌ
1. Muĥammad ibn Ya’qūb and all of my scholars narrated to me from Muĥammad ibn Yaĥyā, from Aĥmad ibn Muĥammad ibn ‘Isā, from Abǐ Yaĥyā Al-Wāsiťi, from someone who said: Abū ‘Abdillāh (Imam Šādiq ) said: (Eating from) any clay is unlawful just like (eating) the flesh of a swine. If anyone eats from any clay which leads to his death, I will not establish prayers on him, except the clay of the grave of Ĥusain , for verily it contains the cure for every disease. (However) anyone who eats it to satisfy a craving will not find any cure in it.
