Sahih Muslim Book - 2, Hadith - 674

و حَدَّثَنَا أَحْمَدُ بْنُ جَوَّاسٍ الْحَنَفِيُّ أَبُو عَاصِمٍ حَدَّثَنَا أَبُو الْأَحْوَصِ عَنْ شَبِيبِ بْنِ غَرْقَدَةَ عَنْ عَبْدِ اللَّهِ بْنِ شِهَابٍ الْخَوْلَانِيِّ قَالَ كُنْتُ نَازِلًا عَلَى عَائِشَةَ فَاحْتَلَمْتُ فِي ثَوْبَيَّ فَغَمَسْتُهُمَا فِي الْمَاءِ فَرَأَتْنِي جَارِيَةٌ لِعَائِشَةَ فَأَخْبَرَتْهَا فَبَعَثَتْ إِلَيَّ عَائِشَةُ فَقَالَتْ مَا حَمَلَكَ عَلَى مَا صَنَعْتَ بِثَوْبَيْكَ؟ قَالَ قُلْتُ رَأَيْتُ مَا يَرَى النَّائِمُ فِي مَنَامِهِ قَالَتْ هَلْ رَأَيْتَ فِيهِمَا شَيْئًا؟ قُلْتُ لَا قَالَتْ فَلَوْ رَأَيْتَ شَيْئًا غَسَلْتَهُ لَقَدْ رَأَيْتُنِي وَإِنِّي لَأَحُكُّهُ مِنْ ثَوْبِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَابِسًا بِظُفُرِي.

It was narrated that 'Abdullah bin Shihab Al-Khawlani said: "I was staying at 'Aishah's house, and I had a wet dream in my garment, so I dipped it in water. A slave girl of 'Aishah saw me and told her, and 'Aishah sent word to me, asking me: 'What made you do that with your garment?' I said: 'I saw what a sleeper sees in his dreams.' She said: 'Did you see something on it (the garment)?' He said: 'No.' She said: 'If you see something, then wash it, for I remember scratching it from the garment of the Messenger of Allah (s.a.w) with my fingernail when it was dry."'
