Chapter 91 | The Clay of the Grave of Ĥusain and Seeking Cure Through It
4 وَ عَنْهُ عَنْ سَعْدِ بْنِ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ أَبِيهِ عَنْ مُحَمَّدِ بْنِ سُلَيْمَانَ الْبَصْرِيِّ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ فِي طِينِ قَبْرِ الْحُسَيْنِ (ع) الشِّفَاءُ مِنْ كُلِّ دَاءٍ وَ هُوَ الدَّوَاءُ الْأَكْبَرُ
4. Muḥammad ibn Ja’far narrated to me from Muḥammad ibn Ḥusain, from a scholar of our companions, from Abil Sabbāḥ Al-Kināni, who said: Abū ‘Abdillāh (Imam Sādiq ) said: The clay of the grave of Ḥusain is a cure even if the clay is collected from the distance of one mile away (from the grave of Ḥusain ).
