Sahih al-Bukhari 6886
Narrated `Aisha:
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."
حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا يَحْيَى، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا مُوسَى بْنُ أَبِي عَائِشَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ لَدَدْنَا النَّبِيَّ صلى الله عليه وسلم فِي مَرَضِهِ فَقَالَ ‏"‏ لاَ تَلُدُّونِي ‏"‏‏.‏ فَقُلْنَا كَرَاهِيَةُ الْمَرِيضِ لِلدَّوَاءِ‏.‏ فَلَمَّا أَفَاقَ قَالَ ‏"‏ لاَ يَبْقَى أَحَدٌ مِنْكُمْ إِلاَّ لُدَّ، غَيْرَ الْعَبَّاسِ فَإِنَّهُ لَمْ يَشْهَدْكُمْ ‏"‏‏.‏
