Abu Abd al-Rahman al-Katib narrated from Muhammad b. ‘Abd Allah al-Zafarani from
Hammad b. Isa from Amir al- Muminin, peace be upon him, who said: When one of
you suffers from Pain of the thighs (al-fakhdhan), let him sit in a large vessel
or basin of heated water and place his hand there [on his thighs] and recite:
Have not the unbelievers then beheld that the heavens and the earth were a mass
all sewn up, and then We unstitched them and of water fashioned every living
thing? Will they not believe?” (21:30).
