Sayyidah Umm al-Mundhir al-Ansariyyah (may Allah be pleased with her), who was one of the maternal aunts of the Messenger of Allah (peace and blessings be upon him), said: The Messenger of Allah (peace and blessings be upon him) came to me, and Ali (may Allah be pleased with him) was with him ((peace and blessings be upon him)). Ali (may Allah be pleased with him) was weak, recovering from an illness, and there was a cluster of dates hanging in the house. The Messenger of Allah (peace and blessings be upon him) ate from it while standing, and Ali (may Allah be pleased with him) was with him ((peace and blessings be upon him)), so he ((peace and blessings be upon him)) said to Ali: "Do not eat from this, for it does not suit you." So he sat down. Then I cooked chard and barley for them, and he ((peace and blessings be upon him)) said: "Eat this, for it suits you better."
