Muhammad b. Hakim narrated from Muhammad b. al-Nadr, a teacher of the child of Abu Ja’far Muhammad b. ‘Ali b. Musa, peace be upon him, that he said: I complained to him [Abu Ja’far] of my suffering from stones. He said: “Woe be to you, what about the ‘comprehensive medication’ of my father?” I said: “My lord and master, describe it for me.” He said: “We have it. Girl, bring out the green container.” He [Muhammad b. al-Nadr] said: She brought it out and he took out a grain of it and said: “Drink this grain with rue water or a decoction of radish (al-fujl) and you will be cured of it.” He [al-Nadr] said: I took the grain with rue water and, by Allah. I have not felt its pain until this day.
