From him, from Mu'awiyah bin Hakim, from Sulayman bin Ja'far Al-Ja'fari, who said: I became ill until I lost my flesh (body mass), so I visited Imam Al-Ridha عليه السلام. Imam عليه السلام said: "Would you like your flesh to return?" I said: “Yes.” Imam عليه السلام said: 'Make it a habit to visit the bathhouse (hammam) every other day (ghibban), and your flesh will return to you. But be careful not to frequent it excessively, for excessive use causes tuberculosis (sill).'"
