An Invocation for the Hamstring and the Sole of the Foot
Abu ‘Atab ‘Abd Allah b. Bistam narrated from Ibrahim b. Muhammad al-Awdi from Safwan al-Jammal from Ja’far b. Muhammad from his father from ‘Ali b. al-Husayn, peace be upon him, who said: A man complained to Abu ‘Abd Allah al-Husayn b. ‘Ali, peace he upon him, and said: “O son of the Messenger of Allah, I suffer from pain in my hamstring (al-urqub) which prevents me from standing up for prayer.” He said: “What prevents you from [reciting] the invocation?” He replied: “I do not know it.”
He said: “When you experience the pain, place your hand there and say: ‘In the Name of Allah, and by Allah, and peace be upon the Messenger of Allah, blessings of Allah on him and his family.’ Then recite over it:
They measure not God with His true measure. The earth altogether shall be His handful on the Day of Resurrection, and the heavens shall he rolled up in His right hand. Glory be to Him! High be He exalted above that they associate! (39:67)”
The man did that and Allah, the Exalted, healed him.
