Hadith 8:97
Abu Bakr narrated to us, he said: Sharik narrated to us, from Ibrahim ibn Muhajir, from Mujahid, who said: Ibn Abbas saw a man while he was insulting his wife, so he said: "What is the matter with you?" He said: "I have emitted madhy (pre-seminal fluid)." Ibn Abbas said: "Do not touch her, and wash yourself for that."
حدثنا أبو بكر قال ثنا شريك عن إبراهيم بن مهاجر عن مجاهد قال رأى بن عباس رجلا وهو يسب امرأته فقال ما لك قال إني أمذيت فقال بن عباس لا تمسها وأهرق لذلك
