I placed water near the Messenger of Allah ﷺ to take a bath because of sexual intercourse. He washed the palms of his bands twice or thrice and then put his hand In the basin and poured water over his private parts and washed them with his left hand. He then struck his hand against the earth and rubbed it with force and then performed ablution for the prayer and then poured three handfuls of water on his head and then washed his whole body after which he moved aside from that place and washed his feet, and then I brought a towel (so that he may wipe his body). but he returned it. (Using translation from Muslim 317a)   

أَدْنَيْتُ لِرَسُولِ اللهِ ﷺ غُسْلَهُ مِنَ الْجَنَابَةِ فَغَسَلَ كَفَّيْهِ مَرَّتَيْنِ أَوْ ثَلَاثًا ثُمَّ أَدْخَلَ كَفَّهُ الْيُمْنَى فِي الْإِنَاءِ فَأَفْرَغَ بِهَا عَلَى فَرْجِهِ فَغَسَلَهُ بِشِمَالِهِ ثُمَّ ضَرَبَ بِشِمَالِهِ الْأَرْضَ فَدَلَكَهَا دَلْكًا شَدِيدًا ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ أَفْرَغَ عَلَى رَأْسِهِ ثَلَاثَ حَفَنَاتٍ مَلَأَ كَفَّيْهِ ثُمَّ غَسَلَ سَائِرَ جَسَدِهِ ثُمَّ تَنَحَّى عَنْ مَقَامِهِ ذَلِكَ فَغَسَلَ رِجْلَيْهِ ثُمَّ أَتَيْتُهُ بِالْمِنْدِيلِ فَرَدَّهُ  

"When the Messenger of Allah ﷺ performed Ghusl from Janabah, he would start by washing his hands, then he would pour water with his right hand onto his left and wash his private part, then he would strike his hand on the ground then wipe it then wash it. Then he would perform Wudu' as for prayer, then he would pour water on his head and all of his body. Then he would move and wash his feet." (Using translation from Nasāʾī 419)   

عَنْ مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ كَانَ النَّبِيُّ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ بَدَأَ فَأَفْرَغَ الْإِنَاءَ عَلَى يَدِهِ فَغَسَلَهَا ثَلَاثًا ثُمَّ يُفْرِغُ بِيَمِينِهِ عَلَى شِمَالِهِ ثُمَّ عَلَى فَرْجِهِ ثُمَّ ضَرَبَ بِيَدِهِ عَلَى الْأَرْضِ فَمَسَحَهَا ثُمَّ غَسَلَهَا ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ أَفْرَغَ عَلَى رَأْسِهِ وَسَائِرِ جَسَدِهِ ثُمَّ تَنَحَّى فَغَسَلَ رِجْلَيْهِ  

The Prophet ﷺ took the bath of Janaba. (sexual relation or wet dream). He first cleaned his private parts with his hand, and then rubbed it (that hand) on the wall (earth) and washed it. Then he performed ablution like that for the prayer, and after the bath he washed his feet. (Using translation from Bukhārī 260)   

أَنَّ النَّبِيَّ ﷺ اغْتَسَلَ مِنَ الْجَنَابَةِ فَغَسَلَ فَرْجَهُ بِيَدِهِ ثُمَّ دَلَكَ بِهَا الْحَائِطَ ثُمَّ غَسَلَهَا ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ فَلَمَّا فَرَغَ مِنْ غُسْلِهِ غَسَلَ رِجْلَيْهِ  

If you want, I can certainly show you the marks of the hand of the Messenger of Allah ﷺ on the wall where he took a bath because of sexual defilement. (Using translation from Abū Dāʾūd 244)   

عَائِشَةُ لَئِنْ شِئْتُمْ لَأُرِيَنَّكُمْ أَثَرَ يَدِ رَسُولِ اللهِ ﷺ فِي الْحَائِطِ حَيْثُ كَانَ يَغْتَسِلُ مِنَ الْجَنَابَةِ
