Hadith 6:128
Hushaym narrated to us, from Mansur, from al-Hasan, who said: He used to say regarding the deceased, if something comes out of him after he has been washed: "He washes what came out of him." He said: And Ibn Sirin used to say: "The washing is repeated upon him."
حدثنا هشيم عن منصور عن الحسن قال كان يقول في الميت إذا خرج منه الشيء بعد غسله قال يغسل ما خرج منه قال وكان بن سيرين يقول يعاد عليه الغسل
