Narrated Sulaiman bin Yasar:
I asked 'Aisha about the clothes soiled with semen. She replied, "I used to wash it off the clothes of Allah's Apostle and he would go for the prayer while water spots were still visible. "
حَدَّثَنَا مُوسَى، قَالَ حَدَّثَنَا عَبْدُ الْوَاحِدِ، قَالَ حَدَّثَنَا عَمْرُو بْنُ مَيْمُونٍ، قَالَ سَأَلْتُ سُلَيْمَانَ بْنَ يَسَارٍ فِي الثَّوْبِ تُصِيبُهُ الْجَنَابَةُ قَالَ قَالَتْ عَائِشَةُ كُنْتُ أَغْسِلُهُ مِنْ ثَوْبِ رَسُولِ اللَّهِ ﷺ، ثُمَّ يَخْرُجُ إِلَى الصَّلاَةِ وَأَثَرُ الْغَسْلِ فِيهِ بُقَعُ الْمَاءِ.

I heard Sulaiman bin Yasar talking about the clothes soiled with semen. He said that 'Aisha had said, "I used to wash it off the clothes of Allah's Apostle and he would go for the prayers while water spots were still visible on them.
حَدَّثَنَا عَمْرُو بْنُ خَالِدٍ، قَالَ حَدَّثَنَا زُهَيْرٌ، قَالَ حَدَّثَنَا عَمْرُو بْنُ مَيْمُونِ بْنِ مِهْرَانَ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنْ عَائِشَةَ، أَنَّهَا كَانَتْ تَغْسِلُ الْمَنِيَّ مِنْ ثَوْبِ النَّبِيِّ ﷺ، ثُمَّ أَرَاهُ فِيهِ بُقْعَةً أَوْ بُقَعًا.
