Sahih Bukhari Volume 7, Book 76, Hadith 5714

قَالَ وَقَالَتْ عَائِشَةُ لَدَدْنَاهُ فِي مَرَضِهِ، فَجَعَلَ يُشِيرُ إِلَيْنَا، أَنْ لاَ تَلُدُّونِي‏.‏ فَقُلْنَا كَرَاهِيَةُ الْمَرِيضِ لِلدَّوَاءِ‏.‏ فَلَمَّا أَفَاقَ قَالَ ‏"‏ أَلَمْ أَنْهَكُمْ أَنْ تَلُدُّونِي ‏"‏‏.‏ قُلْنَا كَرَاهِيَةَ الْمَرِيضِ لِلدَّوَاءِ‏.‏ فَقَالَ ‏"‏ لاَ يَبْقَى فِي الْبَيْتِ أَحَدٌ إِلاَّ لُدَّ ـ وَأَنَا أَنْظُرُ ـ إِلاَّ الْعَبَّاسَ فَإِنَّهُ لَمْ يَشْهَدْكُمْ ‏"

'Aisha added: We put medicine in one side of his mouth but he started waving us not to insert the medicine into his mouth. We said, "He dislikes the medicine as a patient usually does." But when he came to his senses he said, "Did I not forbid you to put medicine (by force) in the side of my mouth?" We said, "We thought it was just because a patient usually dislikes medicine." He said, "None of those who are in the house but will be forced to take medicine in the side of his mouth while I am watching, except Al-'Abbas, for he had not witnessed your deed."
