Emission of semen makes bath obligatory

 ´Abdur-Rahman reported that his father Abu Sa´id Al-Khudri said: I went to Quba with the Messenger of Allah salla alayhi wa sallam on Monday until we reached Banu Salim. The Messenger of Allah salla alayhi wa sallam stood at the door of ´Itban and called him loudly. So he came out dragging his lzar (lower garment). Upon this the Messenger of Allah salla alayhi wa sallam said: ´´We rushed this man out.´´ ltban said: ´´O Messenger of Allah, if a man is rushed out while having an interourse with his wife and separates himself from her before he discharges, what should he do?´´ The Messenger of Allah salla alayhi wa sallam said: ´´The bath becomes obligatory only after seminal discharge.´´
