"I remember when I found it (semen) on the garment of the Messenger of Allah and I scratched it off."
Sunan Ibn Majah Book 1, Hadith 273
← Previous Hadith "A guest came and stayed with 'Aishah, and she ordered that he be given a yellow blanket of hers. He had a nocturnal emission on it, and he felt too shy to send it back to send it back to her when it had the traces of that emission on it, so he dipped it in water and then sent it to her. 'Aishah said: 'Why did he spoil our garment? It would have been sufficient for him to scrape it off with his finger. I often scraped it (semen) from the garment of the Messenger of Allah with my finger.'"

Sunan Ibn Majah Book 1, Hadith 272 Next Hadith → He asked his sister Umm Habibah, the wife of the Prophet: "Did the Messenger of Allah ever offered prayer in a garment in which he had sexual intercourse?" She said: "Yes, if there was nothing noxious on it."
