question #1 Sahih al-Bukhari 1258, 1259, Book 23, Hadith 20 : What are the recommended steps for washing a deceased person in Islamic tradition?

Um ‘Atiyya said, “One of the daughters of the Prophet (ﷺ) died and he came out and said, ‘Wash her three
or five times or more, if you think it necessary, with water and Sidr, and last of all put camphor (or
some camphor) and when you finish, inform me.’ ” Um Atiyya added, “When we finished we
informed him and he gave us his waist-sheet and said, ‘Shroud her in it.’ ” And Um ‘Atiyya (in another
narration) added, “The Prophet (ﷺ) said, ‘Wash her three, five or seven times or more, if you think it
necessary.’ ” Hafsa said that Um ‘Atiyya had also said, “We entwined her hair into three braids.”
