The Book of Prayer - Funerals
Washing the deceased
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ حَفْصَةَ، عَنْ أُمِّ عَطِيَّةَ، . بِنَحْوِهِ غَيْرَ أَنَّهُ قَالَ ثَلاَثًا أَوْ خَمْسًا أَوْ سَبْعًا أَوْ أَكْثَرَ مِنْ ذَلِكِ إِنْ رَأَيْتُنَّ ذَلِكِ . فَقَالَتْ حَفْصَةُ عَنْ أُمِّ عَطِيَّةَ وَجَعَلْنَا رَأْسَهَا ثَلاَثَةَ قُرُونٍ .
A hadith like this has been transmitted by Hafsa on the authority of Umm 'Atiyya with the exception (of these words that the Prophet (ﷺ) asked them to wash her dead body): " three times, five times, seven times, or more than that, if you deem fit:" Hafsa (further) said on the authority of Umm 'Atiyya: We braided (the hair) of her head in three plaits.
