Sayyidah Umm Atiyyah al-Ansariyyah (may Allah be pleased with her) narrates that one of the daughters of the Prophet (peace and blessings be upon him) passed away, so he (peace and blessings be upon him) came to us and said: "Wash her with water and lote-tree leaves, and wash her an odd number of times, three or five, or even more than that if you see the need, and in the last washing put camphor, or some camphor; and when you have finished, tell me." She says: When we had finished, we informed him (peace and blessings be upon him), and he (peace and blessings be upon him) gave us a waist-wrapper and said: "Wrap her in it next to her body." Umm Atiyyah (may Allah be pleased with her) says: We braided her hair into three plaits, then we placed her front plait and her two side plaits behind her.
