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
