The Medication For The Belly

Muhammad b. ‘Abd Allah al-Katib narrated from Ahmad b. lshaq, who said: I would often sit with Al-Ridha’, peace be upon him. I said to him: “O son of the Messenger of Allah, my father has been suffering from an ailment of the belly for three nights and he cannot control it.” He said: “What about the ‘comprehensive medication’?” I replied: “I do not know it.” He said: “Ahmad b. Ibrahim al-Tammar knows it. Take one grain of it and give it to your father to drink with a decoction of myrtle. He will recover at once.” He [Ahmad b. Ishaq] said: I went to him [al-Tammar] and took from him a large amount. I gave my father one grain of it and he found relief immediately.
