قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «فِي طِينِ قَبْرِ اَلْحُسَيْنِ عَلَيْهِ اَلسَّلاَمُ شِفَاءٌ مِنْ كُلِّ دَاءٍ وَ هُوَ اَلدَّوَاءُ اَلْأَكْبَرُ.
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "In the clay of the grave of al-Husayn (a.s) is healing for every ailment, and it is the greatest remedy."
