Umm 'Atiyah (RAA) narrated, 'The Messenger of Allah (ﷺ) came to us when we were washing his daughter (Zainab) after she had died and said, "Wash her three times, five times or more if necessary, with water and lotus leaves (Sidr) and apply some camphor to the last washing." When we finished making Ghusl for her, we informed the Messenger of Allah (ﷺ) and he threw his Izar (a cloth, which he wore round his waist) to us and told us to wrap her in it as the first sheet of the shroud (next to her body).' Agreed upon. In another narration, "Start by washing the organs on the right and those parts that are washed in ablution." In the narration of Al-Bukhari, "We braided her hair in three braids and made them fall at her back."
