One of the daughters of the Prophet ﷺ passed away, and he sent word to us, saying, "Wash her three times, or five, or more than that if you think it necessary, with water and lotus leaves, and put camphor, or a little camphor, in the final washing. When you have finished, let me know."When we had finished, we informed him, and he handed us his waist-wrapper and said, "Wrap her in this next to her body."He said, "Three times, or five, or seven, or more than that if you think it necessary."
أخبرنا قتيبة قال حدثنا حماد عن أيوب عن حفصة عن أم عطية نحوه غير أنه قال ثلاثا أو خمسا أو سبعا أو أكثر من ذلك إن رأيتن ذلك
