أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ غَسَلَ يَدَيْهِ ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ ثُمَّ اغْتَسَلَ ثُمَّ يُخَلِّلُ بِيَدِهِ شَعْرَهُ حَتَّى إِذَا ظَنَّ أَنَّهُ قَدْ أَرْوَى بَشَرَتَهُ أَفَاضَ عَلَيْهِ الْمَاءَ ثَلاَثَ مَرَّاتٍ ثُمَّ غَسَلَ سَائِرَ جَسَدِهِ ‏.‏
