Woman exciting herself to the point of climax

If a woman excites herself to the point of climax, it is
obligatory (waajib) for her to do ghusl, and she is considered to be junub (in a state of
sexual impurity) because of that. The Prophet
(peace and blessings of Allaah be upon him)
said: “Water is for water” (Saheeh Muslim, 151), i.e., ghusl becomes waajib when
fluid is emitted as a result of sexual stimulation.

But this action – when a person excites herself or himself to the
point of climax – is masturbation, which is forbidden for men and women alike. There
is no differentiation between them in this regard. For more information and explanation of
the evidence (daleel), please see Question #329.

And Allaah knows best.
