Hadith no. 279 is a repeat. Read it here.
(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.”
- Yes, women can have wet dreams as well.
- If discharge is noticed, taking a bath (that of Janaba) is compulsory.
- The discharge noticed has to be due to a dream (while sleeping). Getting it while being awake does not have the same ruling.
