Sunan an-Nasa'i, Volume 3, Book 21, Hadith 1890 (DarusSalam) ⓘ

It was narrated that Umm 'Atiyyah said: "A daughter of the Messenger of Allah died and he told us to wash her. He said: 'Three times, or five or seven, or more than that, if you think that (is necessary).' I said: 'An odd number?' He said: 'Yes, and put camphor, or some camphor, in (the water) the last time. And when you have finished, inform me.' So when you have finished, we informed him, and then gave us his waist-wrap and said: 'Shroud her in it."

أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا بِشْرٌ، عَنْ سَلَمَةَ بْنِ عَلْقَمَةَ، عَنْ مُحَمَّدٍ، عَنْ بَعْضِ، إِخْوَتِهِ عَنْ أُمِّ عَطِيَّةَ، قَالَتْ تُوُفِّيَتِ ابْنَةٌ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَأَمَرَنَا بِغَسْلِهَا فَقَالَ ‏"‏ اغْسِلْنَهَا ثَلاَثًا أَوْ خَمْسًا أَوْ سَبْعًا أَوْ أَكْثَرَ مِنْ ذَلِكِ إِنْ رَأَيْتُنَّ ‏"‏ ‏.‏ قَالَتْ قُلْتُ وِتْرًا قَالَ ‏"‏ نَعَمْ وَاجْعَلْنَ فِي الآخِرَةِ كَافُورًا أَوْ شَيْئًا مِنْ كَافُورٍ فَإِذَا فَرَغْتُنَّ فَآذِنَّنِي ‏"‏ ‏.‏ فَلَمَّا فَرَغْنَا آذَنَّاهُ فَأَعْطَانَا حَقْوَهُ وَقَالَ ‏"‏ أَشْعِرْنَهَا إِيَّاهُ ‏"‏ ‏.‏
