Sunan Abi Dawud, Hadith 244 ⓘ
Narrated Aisha, Ummul Mu'minin: If you want, I can certainly show you the marks of the hand of the Messenger of Allah on the wall where he took a bath because of sexual defilement.
حَدَّثَنَا الْحَسَنُ بْنُ شَوْكَرٍ، حَدَّثَنَا هُشَيْمٌ، عَنْ عُرْوَةَ الْهَمْدَانِيِّ، حَدَّثَنَا الشَّعْبِيُّ، قَالَ قَالَتْ عَائِشَةُ رضى الله عنها لَئِنْ شِئْتُمْ لأُرِيَنَّكُمْ أَثَرَ يَدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْحَائِطِ حَيْثُ كَانَ يَغْتَسِلُ مِنَ الْجَنَابَةِ .
