Umm 'Atiyya reported:

The Messenger of Allah (ﷺ) came to us when we were bathing his daughter, and he told us: Wash her with water and (with the leaves of) the lote tree, three or five times, or more than that if you think fit, and put camphor or something like camphor in the last washing; then inform me when you have finished. So when we had finished, we informed him, and he gave to us his (own) under-garment saying:" Put it next her body."

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أُمِّ عَطِيَّةَ، قَالَتْ دَخَلَ عَلَيْنَا النَّبِيُّ صلى الله عليه وسلم وَنَحْنُ نَغْسِلُ ابْنَتَهُ فَقَالَ ‏"‏ اغْسِلْنَهَا ثَلاَثًا أَوْ خَمْسًا أَوْ أَكْثَرَ مِنْ ذَلِكَ إِنْ رَأَيْتُنَّ ذَلِكَ بِمَاءٍ وَسِدْرٍ وَاجْعَلْنَ فِي الآخِرَةِ كَافُورًا أَوْ شَيْئًا مِنْ كَافُورٍ فَإِذَا فَرَغْتُنَّ فَآذِنَّنِي ‏"‏ ‏.‏ فَلَمَّا فَرَغْنَا آذَنَّاهُ فَأَلْقَى إِلَيْنَا حِقْوَهُ فَقَالَ ‏"‏ أَشْعِرْنَهَا إِيَّاهُ ‏"‏ ‏.‏
