We poured medicine into the mouth of the Prophet (ﷺ) during his ailment. He said, "Don't pour medicine
into my mouth." (We thought he said that) out of the aversion a patient usually has for medicines.
When he improved and felt better he said, "There is none of you but will be forced to drink medicine,
except Al-`Abbas, for he did not witness your deed."
Sahih al-Bukhari Book 87, Hadith 25
