Tradition 1: Imam As-Sadiq (‘a) said: The clay of Imam Al-Husayn's ('a) grave is a cure for every disease. When you eat it, recite the following:

Translation: In the name of Allah and by Allah. O Allah! Make it (the cause of) extensive sustenance and beneficial knowledge (for me) and make it my cure from every disease. Indeed, You have power over all things.

Tradition 2: When you eat the clay of Imam Al-Husayn's ('a) grave, you should recite:

اللَّهُمَّ رَبَّ هَذِهِ التُّرْبَةِ الْمُبَارَكَةِ وَ رَبَّ هَذَا الْوَصِيِّ الَّذِي وَارَتْهُ صَلِّ عَلَى مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ اجْعَلْهُ عِلْماً نَافِعاً وَ رِزْقاً وَاسِعاً وَ شِفَاءً مِنْ كُلِّ دَاءٍ.

Translation: O Lord of this blessed dust! And O Lord of this successor who is buried in it! Bless Muhammad and Aali Muhammad and make it the cause of beneficial knowledge and extensive sustenance for me and my cure from every disease.

Tradition 3: Imam As-Sadiq (‘a) said: When you collect the clay of the Imam Al-Husayn ('a) and place it in your mouth, recite:

اللَّهُمَّ إِنِّي أَسْأَلُكَ بِحَقِّ هَذِهِ التُّرْبَةِ وَ بِحَقِّ الْمَلَكِ الَّذِي قَبَضَهَا وَ النَّبِيِّ الَّذِي حَضَنَهَا وَ الْإِمَامِ الَّذِي حَلَّ فِيهَا أَنْ تُصَلِّيَ عَلَى مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ أَنْ تَجْعَلَ لِي فِيهَا شِفَاءً نَافِعاً وَ رِزْقاً وَاسِعاً وَ أَمَاناً مِنْ كُلِّ خَوْفٍ وَ دَاءٍ

Translation: O Allah! I ask You through the right of this dust, through the right of the angel who held it, through the right of the Prophet who embraced it and through the right of the Imam who is buried in it to bless Muhammad and Aali Muhammad and to allow it to be a beneficial cure and an extensive sustenance for me and (allow it) to be my protection against any fear and disease.

If you recite this, Allah will cure you and bestow you with health.
