Musnad Ahmad Hadith 27469

It is narrated from Asma (may Allah be pleased with her) that the Prophet (ﷺ) first fell ill in the house of Maymunah (may Allah be pleased with her). The illness of the Prophet (ﷺ) increased, until he became unconscious. The pure wives consulted among themselves about giving medicine to the blessed mouth of the Prophet (ﷺ), so they put medicine in the blessed mouth of the Prophet (ﷺ). When the Prophet (ﷺ) regained consciousness, he asked: "What is this?" We submitted that this is the work of your pure wives who have come from here, and pointed towards the land of Abyssinia. Among them was Asma bint Umais (may Allah be pleased with her) as well. She submitted: O Messenger of Allah! We thought that you were suffering from the illness of pleurisy. The Prophet (ﷺ) said: This is such an illness that Allah Almighty will never afflict me with. No one should remain in this house whose mouth is not given medicine, except for the uncle of the Prophet (ﷺ), that is, Abbas (may Allah be pleased with him). Thus, on that day, medicine was put in the mouth of Maymunah (may Allah be pleased with her), even though she was fasting that day, because the Prophet (ﷺ) had given a very strict order for it.
