For Ailments of the Belly and the Prayer For It
Ahmad b. ‘Abd al-Rahman b. Jamila narrated from al-Hasan b. Khalid, who said: I wrote to Abu al-Hasan, peace be upon him, complaining of an ailment in my belly and asking for a prayer.
He wrote: “In the Name of Allah, the Merciful, the Compassionate.” He wrote the first sura of the Qur'an, the two suras of taking refuge al-Falaq (113) and al-Nas (114), and the sura al-Ikhlas (112). Then he wrote under that:
“I take refuge in the Face of Allah, the Magnificient, and His Might, which is unceasing, and His Power, which nothing can resist, from the evil of this pain and the evil of what is in it and what I fear.”
[He said:] “Write that on a tablet or a shoulder-blade, then wash it out with rainwater and drink it before breakfast and before bed. Write below that: ‘He made it a healing from every illness.’”
