"I asked Sulaiman bin Yasar about a garment which gets semen on it. 'Should I wash it off or wash the entire garment?' Sulaiman said: 'Aishah said: "Semen used to get on the garment of the Messenger of Allah and he would wash it off his garment, then he would go out to pray wearing that garment, and I could see the marks left on it by washing."  

ابن ماجة:٥٣٦حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ عَنْ عَمْرِو بْنِ مَيْمُونٍ قَالَ سَأَلْتُ سُلَيْمَانَ بْنَ يَسَارٍ

عَنِ الثَّوْبِ يُصِيبُهُ الْمَنِيُّ أَنَغْسِلُهُ أَوْ نَغْسِلُ الثَّوْبَ كُلَّهُ قَالَ سُلَيْمَانُ قَالَتْ عَائِشَةُ كَانَ النَّبِيُّ ﷺ يُصِيبُ ثَوْبَهُ فَيَغْسِلُهُ مِنْ ثَوْبِهِ ثُمَّ يَخْرُجُ فِي ثَوْبِهِ إِلَى الصَّلاَةِ وَأَنَا أَرَى أَثَرَ الْغُسْلِ فِيهِ

I asked Sulaiman b. Yasar whether the semen that gets on to the garment of a person should be washed or not. He replied: A'isha told me: The Messenger of Allah ﷺ washed the semen, and then went out for prayer in that very garment and I saw the mark of washing on it.
