Hammam b. al-Harith reported, he has a sexual dream when he was staying with 'Aishah. The slave girl of 'Aishah saw him while he was washing the mark of defilement, or he was washing his clothe. She informed 'Aishah who said:

He witnessed me rubbing off the semen from the clothe of the Messenger of Allah ﷺ.

Abu Dawud said: Al-A'mash narrated it as narrated by al-Hakam.

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، عَنْ شُعْبَةَ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ هَمَّامِ بْنِ الْحَارِثِ، أَنَّهُ كَانَ عِنْدَ عَائِشَةَ - رضى الله عنها - فَاحْتَلَمَ فَأَبْصَرَتْهُ جَارِيَةٌ لِعَائِشَةَ وَهُوَ يَغْسِلُ أَثَرَ الْجَنَابَةِ مِنْ ثَوْبِهِ أَوْ يَغْسِلُ ثَوْبَهُ فَأَخْبَرَتْ عَائِشَةَ فَقَالَتْ لَقَدْ رَأَيْتُنِي وَأَنَا أَفْرُكُهُ مِنْ ثَوْبِ رَسُولِ اللَّهِ ﷺ . قَالَ أَبُو دَاوُدَ رَوَاهُ الأَعْمَشُ كَمَا رَوَاهُ الْحَكَمُ .
