When Afflicted with Calamity or Disease

O Mohammad, and whoever is afflicted with the trials of illness, he should descend me in it and say:

يَا مُصِحَّ أَبْدَانِ مَلاَئِكَتِهِ وَ يَا مُفَرِّغَ تِلْكَ الْاَبْدَانِ لِطَاعَتِهِ وَ يَا خَالِقَ الاْدَمِيِّينَ صَحِيحاً وَ مُبْتَلًى وَ يَا مُعَرِّضَ أَهْلِ السُّقْمِ وَ أَهْلِ الصِّحَّةِ لِلْاَجْرِ وَ الْبَلِيَّةِ وَ يَا مُدَاوِيَ الْمَرْضَى وَ شَافِيَهُمْ وَ يَا مُصِحَّ أَهْلِ السُّقْمِ بِإِلْبَاسِهِمْ عَافِيَتَهُ بِطِبِّهِ وَ يَا مُفَرِّجُ [مُفَرِّجاً] عَنْ أَهْلِ الْبَلاَءِ بَلاَيَاهُمْ بِجَلِيلِ رَحْمَتِهِ، قَدْ نَزَلَ بِي مِنَ الْاَمْرِ مَا رَفَضَنِي فِيهِ أَقَارِبِي وَ أَهْلِي وَ الصَّدِيقُ وَ الْبَعِيدُ وَ مَا شَمِتَ بِي فِيهِ أَعْدَائِي حَتَّى صِرْتُ مَذْكُوراً بِبَلاَئِي فِي أَفْوَاهِ الْمَخْلُوقِينَ، وَ أَعْيَتْنِي أَقَاوِيلُ أَهْلِ الْاَرْضِ لِقِلَّةِ عِلْمِهِمْ بِدَوَاءِ دَائِي وَ طِبُّ دَوَائِي فِي عِلْمِكَ عِنْدَكَ مُثْبَتٌ، صَلِّ عَلَى مُحَمَّد وَ آلِ مُحَمَّد وَ انْفَعْنِي بِطِبِّكَ، فَلاَ طَبِيبَ أَرْجَى عِنْدِي مِنْكَ وَ لاَ حَمِيمَ أَشَدُّ تَعَطُّفاً مِنْكَ عَلَيَّ قَدْ غَيَّرَتْ بَلِيَّتُكَ نِعَمَكَ عَلَيَّ، فَحَوِّلْ ذَلِكَ عَنِّي إِلَى الْفَرَجِ وَ الرَّخَاءِ، فَإِنَّكَ إِنْ لَمْ تَفْعَلْ لَمْ أَرْجُهُ مِنْ غَيْرِكَ، فَانْفَعْنِي بِطِبِّكَ وَ دَاوِنِي بِدَوَائِكَ يَا رَحِيمُ. 

O Restorer of the bodies of His angels, and O Unloader of those bodies for His obedience, and O Creator of humans, sound and afflicted, and O You Exposer of the people of illness and the people of health for reward and affliction, and O Therapist of the sick and their Healer, and O Restorer of the ill people by clothing them in Your healing through Your therapy, and O Reliever of the people of tribulation from their tribulations through the majesty of His mercy. Indeed, I have been afflicted with a matter that has caused me to be abandoned by my relatives, family, friends, acquaintance, and even my enemies have taunted me in it, to the extent that I have become known for my affliction among all of creation. The words of the people of this earth have exhausted me due to their lack of knowledge about the cure for my ailment. But the medicine for my cure is established in Your knowledge. So, bless Mohammad and the family of Mohammad, and benefit me with Your medicine, for there is no physician I hope for more than You, nor a close one more compassionate towards me than You. Your affliction has changed Your blessings upon me, so turn that into relief and ease, for if You do not do so, I will never hope for it from anyone else. So, benefit me with Your medicine and treat me with Your remedy, O Most Merciful.

For indeed, as he says that, I drive away his harm from him and grant him healing from it.
