Jami` at-Tirmidhi Book 10, Hadith 54
"When the Messenger of Allah died, they disagreed over where to bury him. So Abu Bakr said: 'I heard the Messenger of Allah saying something which I have not forgotten, he said: "Allah does not take (the life of ) a Prophet except at the location in which He wants him to be buried.'" So they buried him at the spot of his bed."
"The Messenger of Allah would visit the sick, attend the funerals, ride a donkey, accept the invitation of a slave, and on the Day of Banu Quraizah he was on a donkey muzzled with a cord of fibers and a pack-saddle made of fibers."
The Messenger of Allah said: "Mention good things about your dead, and refrain from (mentioning) their evil."
