A Dua For Healing Every Pain

Khaled ibn Isa said: Imam Reza (A.S) taught me this supplication and said: teach it to your faithful brothers as it heals every pain. 

أُعِيذُ نَفْسِي بِرَبِّ الاَْرْضِ وَ رَبِّ السَّمَاءِ أُعِيذُ نَفْسِي بِالَّذِي لاَ يَضُرُّ مَعَ اسْمِهِ دَاءٌ، أُعِيذُ نَفْسِي بِالَّذِي اسْمُهُ بَرَكَةٌ وَ شِفَاءٌ. 

I seek my soul/self to be protected by the Lord of the earth and the Lord of the sky, I invoke the protection of who no disease would harm with His name upon my soul, I invoke the protection of who His name is the blessing and healing upon my soul.
