Washing Semen From A Garment
Sunan an-Nasai
أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ عَمْرِو بْنِ مَيْمُونٍ الْجَزَرِيِّ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَغْسِلُ الْجَنَابَةَ مِنْ ثَوْبِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَيَخْرُجُ إِلَى الصَّلاَةِ وَإِنَّ بُقَعَ الْمَاءِ لَفِي ثَوْبِهِ .
It was narrated that 'Aishah said: "I used to wash the Janabah from the garment of the Messenger of Allah (ﷺ) and he would go out to pray, with traces of water on his garment."
