بَابُ مَنْ تَوَضَّأَ فِي الْجَنَابَةِ ثُمَّ غَسَلَ سَائِرَ جَسَدِهِ، وَلَمْ يُعِدْ، غَسْلَ مَوَاضِعِ الْوُضُوءِ مَرَّةً أُخْرَى
Sahih al-Bukhari 274

Narrated Maimuna:

Water was placed for the ablution of Allah's Messenger (ﷺ) after Janaba. He poured water with his right hand over his left twice or thrice and then washed his private parts and rubbed his hand on the earth or on a wall twice or thrice and then rinsed his mouth, washed his nose by putting water in it and then blowing it out and then washed his face and forearms and poured water over his head and washed his body. Then he shifted from that place and washed his feet. I brought a piece of cloth, but he did not take it and removed the traces of water from his body with his hand."

حَدَّثَنَا يُوسُفُ بْنُ عِيسَى، قَالَ أَخْبَرَنَا الْفَضْلُ بْنُ مُوسَى، قَالَ أَخْبَرَنَا الأَعْمَشُ، عَنْ سَالِمٍ، عَنْ كُرَيْبٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ، عَنْ مَيْمُونَةَ، قَالَتْ وَضَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَضُوءًا لِجَنَابَةٍ فَأَكْفَأَ بِيَمِينِهِ عَلَى شِمَالِهِ مَرَّتَيْنِ، أَوْ ثَلاَثًا، ثُمَّ غَسَلَ فَرْجَهُ، ثُمَّ ضَرَبَ يَدَهُ بِالأَرْضِ ـ أَوِ الْحَائِطِ ـ مَرَّتَيْنِ أَوْ ثَلاَثًا، ثُمَّ مَضْمَضَ وَاسْتَنْشَقَ، وَغَسَلَ وَجْهَهُ وَذِرَاعَيْهِ، ثُمَّ أَفَاضَ عَلَى رَأْسِهِ الْمَاءَ، ثُمَّ غَسَلَ جَسَدَهُ، ثُمَّ تَنَحَّى فَغَسَلَ رِجْلَيْهِ‏.‏ قَالَتْ فَأَتَيْتُهُ بِخِرْقَةٍ، فَلَمْ يُرِدْهَا، فَجَعَلَ يَنْفُضُ بِيَدِهِ‏.‏
