Al-Ladud (the medicine which is poured or inserted into one side of a patient's mouth)
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي مُوسَى بْنُ أَبِي عَائِشَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، وَعَائِشَةَ، أَنَّ أَبَا بَكْرٍ ـ رضى الله عنه ـ قَبَّلَ النَّبِيَّ صلى الله عليه وسلم وَهْوَ مَيِّتٌ. 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 ".
Narrated Ibn `Abbas and `Aisha: Abu Bakr kissed (the forehead of) the Prophet (ﷺ) when he was dead. `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."
