One-fifth of Booty to the Cause of Allah (Khumus)

Bukhari :: Book 4 :: Volume 53 :: Hadith 332

Narrated Ibn Abu Mulaika:

'Aisha said, "The Prophet 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 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."
