حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ ، عَنْ هِشَامِ بْنِ حَسَّانٍ , قَالَ : حَدَّثَتْنَا حَفْصَةُ ، عَنْ أُمِّ عَطِيَّةَ رَضِيَ اللَّهُ عَنْهَا , قَالَتْ : " تُوُفِّيَتْ إِحْدَى بَنَاتِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَأَتَانَا النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , فَقَالَ : اغْسِلْنَهَا بِالسِّدْرِ وِتْرًا ثَلَاثًا أَوْ خَمْسًا أَوْ أَكْثَرَ مِنْ ذَلِكَ إِنْ رَأَيْتُنَّ ذَلِكَ وَاجْعَلْنَ فِي الْآخِرَةِ كَافُورًا أَوْ شَيْئًا مِنْ كَافُورٍ ، فَإِذَا فَرَغْتُنَّ فَآذِنَّنِي ، فَلَمَّا فَرَغْنَا آذَنَّاهُ فَأَلْقَى إِلَيْنَا حِقْوَهُ فَضَفَرْنَا شَعَرَهَا ثَلَاثَةَ قُرُونٍ وَأَلْقَيْنَاهَا خَلْفَهَا " .
Narrated Um 'Atiyya: One of the daughters of the Prophet expired and he came to us and said, "Wash her with Sidr (water) for odd number of times, i.e. three, five or more, if you think it necessary, and in the last, put camphor or (some camphor on her), and when you finish, notify me." So when we finished we informed him. He gave his waist-sheet to us (to shroud her). We entwined the hair (of the deceased girl) in three braids and made them fall at her back.
