Answered by Shaykh Faraz Rabbani
When the husband masturbates his wife and inserts his fingers in her vagina, does it necessitate ghusl for her? What is the ruling if she omits liquids or has an orgasm, and what if she does not?

Walaikum assalam,
If she has an orgasm, she must perform ghusl.
If not, no.

Walaikum assalam,
Faraz Rabbani.
