Answered by Shaykh Faraz Rabbani
Do female orgasms without penetration require ghusl?
Walaikum assalam wa rahmatullah,
Any orgasm that is accompanied by sexual desire (actual or effective), whether accompanied by penetration or not, requires ghusl. [Radd al-Muhtar]
“A purificatory bath is necessitated by:
a) sperm or female ejaculate that leaves its place of origin with desire [f: whether actual or effective], even if it exits the body without desire, even if without sexual intercourse;
b) the head of the penis entering either private part of a living human being who is fit for sexual intercourse, even without any release of sexual fluids ” [al-Hadiyya al-`Ala’iyya, ]
