The Book of Menstruation (Kitab Al-Haid)
Muslim :: Book 3 : Hadith 607
Anas b. Malik reported: Umm Sulaim who was the grandmother of Ishaq came to the Messenger of Allah (may peace be upon him) in the presence of 'A'isha and said to him: Messenger of Allah, in case or woman sees what a man sees in dream and she experiences in dream what a man experiences (i. e. experiences orgasm)? Upon this 'A'isha remarked: O Umm Sulaim, you brought humiliation to women;may your right hand be covered with dust. He (the Holy Prophet) said to 'A'isha: Let your hand be covered with dust, and (addressing Umm Sulaim) said: Well, O Umm Sulaim, she should take a bath if she sees that (i. e. she experiences orgasm in dream).
