Sa'id al-Khudri narrated it from his father:
I went to Quba' with the Messenger of Allah ( صلی اللہ علیہ وسلم ) on Monday till we reached (the habitation) of Banu Salim. The Messenger of Allah ( صلی اللہ علیہ وسلم ) stood at the door of 'Itban and called him loudly. So he came out dragging his lower garnment. Upon this the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: We have made this man to make haste 'Itban said: Messenger of Allah, if a man parts with his wife suddenly without seminal emission, what is he required to do (with regard to bath)? The Messenger of Allah ( صلی اللہ علیہ وسلم ) said: It is with the seminal emission that bath becomes obligatory.
