Dietary restriction for the sick

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both), who said: None of you should stop a patient from eating food that the patient craves; perhaps Allah Almighty will cure him, for Allah Almighty creates cure wherever He wills.

It is narrated from Sayyidah Umm al-Mundhir al-Adawiyyah (may Allah be pleased with her), who said: The Prophet (peace and blessings be upon him) came to my home, and with him (peace and blessings be upon him) was Sayyiduna Ali (may Allah be pleased with him), who was weak after recovering from illness. We had half-ripe dates hanging. Sayyidah Umm al-Mundhir said: The Messenger of Allah (peace and blessings be upon him) stood up and (peace and blessings be upon him) ate of the dates, and Sayyiduna Ali (may Allah be pleased with him) also stood up and began to eat. The Prophet (peace and blessings be upon him) said: "Leave it, for you are weak." The narrator said: So Sayyiduna Ali (may Allah be pleased with him) sat down, and the Prophet (peace and blessings be upon him) went on eating of those dates. Then I (Umm al-Mundhir) cooked greens and barley for them, and the Prophet (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "Eat from this."

Ja'far narrates from his father, who said: A tray of dates was presented to the Prophet (peace and blessings be upon him) as a gift, and Sayyiduna Ali (may Allah be pleased with him) was feverish at the time. The narrator said: He (peace and blessings be upon him) tossed a date to Sayyiduna Ali (may Allah be pleased with him), then tossed another, until he (peace and blessings be upon him) had given him seven dates. Then he (peace and blessings be upon him) held back his hand and said: "These are enough for you."
