Sahih Bukhari, Chapter: Funerals (Al-Janaaiz)

Um Atiyya (an Ansari woman who gave the pledge of allegiance to the Prophet[saw]) came to Basra to visit her son, but she could not find him. She narrated to us, "The Prophet (saw) came to us while we were giving bath to his (dead) daughter, he said: 'Wash her three times, five times or more, if you think it necessary, with water and Sidr, and last of all put camphor, and when you finish, notify me.'" Um Atiyya added, "After finishing, we informed him and he gave us his waist sheet and told us to shroud her in it and did not say more than that."
