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-ʿAbbas, for he did not witness your deed." (Using translation from Bukhārī 6886)  

لَدَدْنَا رَسُولَ اللهِ ﷺ فِي مَرَضِهِ قَالَ «لَا تَلُدُّونِي» قُلْنَا كَرَاهِيَةَ الْمَرِيضِ لِلدَّوَاءِ فَلَمَّا أَفَاقَ قَالَ «لَا يَبْقَى أَحَدٌ مِنْكُمْ إِلَّا لُدُّ غَيْرَ الْعَبَّاسِ فَإِنَّهُ لَمْ يَشْهَدْكُمْ»
