What is the ruling on a woman bringing about her own discharge by hand after intercourse due to the husband's impatience or his premature ejaculation, with emphasis that this is not for the purpose of seeking pleasure, but only for the stage of discharge?

It is incumbent upon the spouses to strive for each other's chastity and to bring joy. It is impermissible to use prohibited means to fulfill desires. Therefore, it is not permissible for a woman to use her own hand for that purpose. However, using the husband's hand is permissible.
