Abu Ghiyas ‘Abd Allah b. Bistam narrated from ‘Abd Allah b. Ibrahim from Muhammad b. al-Jahm from Ibrahim b. al-Hasan al-Ja’fari from Abu ‘Abd Allah, peace be upon him, who said to his companions: “Tell me, with what do your physicians instruct you to eat citron (al-utrujj)?” He replied: “O son of the Messenger of Allah, they instruct us to eat it before meals.” He said: “There is nothing more beneficial than it after a meal. Eat its preserves (al-murabba), for its pit has a fragrance like the fragrance of musk.”

He, peace be upon him, said in another report: “It is good before meals but even better after meals.” Then he said: “It causes harm before the meal and is beneficial after the meal. Dry cheese digests citron.”
