Sunan an-Nasa'i 246
It was narrated that Abu Salamah bin 'Abdur-Rahman said:
"Aishah described how the Prophet (ﷺ) performed Ghusl for Janabah. She said: 'He used to wash his hands three times, then pour water with his right hand onto his left and wash his private part and whatever was on it.' - (One of the narrators) 'Umar said: "I think he said: 'He would pour water with his right hand onto his left hand three times.'" - "Then he would rinse his mouth three times and his nose three times, and wash his face and hands three times, then he would pour water over his head three times, then pour water over himself.'"
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا عُمَرُ بْنُ عُبَيْدٍ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ وَصَفَتْ عَائِشَةُ غُسْلَ النَّبِيِّ صلى الله عليه وسلم مِنَ الْجَنَابَةِ قَالَتْ كَانَ يَغْسِلُ يَدَيْهِ ثَلاَثًا ثُمَّ يُفِيضُ بِيَدِهِ الْيُمْنَى عَلَى الْيُسْرَى فَيَغْسِلُ فَرْجَهُ وَمَا أَصَابَهُ - قَالَ عُمَرُ وَلاَ أَعْلَمُهُ إِلاَّ قَالَ يُفِيضُ بِيَدِهِ الْيُمْنَى عَلَى الْيُسْرَى ثَلاَثَ مَرَّاتٍ - ثُمَّ يَتَمَضْمَضُ ثَلاَثًا وَيَسْتَنْشِقُ ثَلاَثًا وَيَغْسِلُ وَجْهَهُ ثَلاَثًا ثُمَّ يُفِيضُ عَلَى رَأْسِهِ ثَلاَثًا ثُمَّ يَصُبُّ عَلَيْهِ الْمَاءَ ‏.‏
