650. hadíth
4 وَ رَوَى سَمَاعَةُ بْنُ مِهْرَانَ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ كُلُّ طِينٍ حَرَامٌ عَلَى بَنِي آدَمَ مَا خَلَا طِينَ قَبْرِ الْحُسَيْنِ (ع) مَنْ أَكَلَهُ مِنْ وَجَعٍ شَفَاهُ اللَّهُ تَعَالَى
4. Samā’ah ibn Mihrān narrated that: Abū ‘Abdillāh (Imam Sādiq (a.s.)) said: (Eating from) any clay is unlawful for mankind except (eating from) the clay of the grave of Ḥusain (a.s.). Allāh, the Exalted, will cure those who eat from it to treat an illness.
