What did Prophet Muhammad (peace be upon him) say regarding the necessity of a woman taking a bath after a wet dream (nocturnal sexual discharge)?
 Narrated Um-Salama:                     (the mother of the believers) Um Sulaim, the wife of Abu Talha, came to Allah's Apostle and said, "O Allah's Apostle! Verily Allah is not shy of (telling you) the truth. Is it necessary for a woman to take a bath after she has a wet dream (nocturnal sexual discharge)?" Allah's Apostle replied, "Yes, if she notices a discharge."
