`Aisha said, "The Prophet (ﷺ) died in my house on the day of my turn while he was leaning on my chest closer to my neck, and Allah made my saliva mix with his Saliva." `Aisha added, "`AbdurRahman came with a Siwak and the Prophet (ﷺ) was too weak to use it so I took it, chewed it and then (gave it to him and he) cleaned his teeth with it."
Sahih al-Bukhari Book 57, Hadith 9
← Previous Hadith (the wife of the Prophet) When the sickness of Allah's Messenger (ﷺ) got aggravated, he asked the permission of his wives that he should be treated in my house, and they permitted him.

Sahih al-Bukhari Book 57, Hadith 8 Next Hadith → (the wife of the Prophet) That she came to visit Allah's Messenger (ﷺ) while he was in I`tikaf (i.e. seclusion in the Mosque during the last ten days of Ramadan). When she got up to return, Allah's Messenger (ﷺ) got up with her and accompanied her, and when he reached near the gate of the Mosque close to the door (of the house) of Um Salama, the wife of the Prophet, two Ansari men passed by them and greeted Allah's Apostle and then went away. Allah's Messenger (ﷺ) addressed them saying, "Don't hurry! (She is my wife)," They said, "Glorified be Allah! O Allah's Messenger (ﷺ) (You are far away from any suspicion)," and his saying was hard on them. Allah's Messenger (ﷺ) said, "Satan circulates in the mind of a person as blood does (in his body). I was afraid that Satan might put some (evil) thoughts in your minds."
