Sahih Bukhari Volume 2, Book 23, Hadith Number 344.

Narated By Um ‘Atiyya al-Ansariya : Allah’s Apostle came to us when his daughter died and said, “Wash her thrice or five times or more, if you see it necessary, with water and Sidr and then apply camphor or some camphor at the end; and when you finish, notify me.” So when we finished it, we informed him and he gave us his waist-sheet and told us to shroud the dead body in it.
