Is it permissible for a man to masturbate with his wife's hand during the postpartum period or otherwise, and what are the forbidden or reprehensible ways of marital intercourse?

A man may enjoy his wife as he wishes, except in two situations: anal intercourse, as the one who commits this act is cursed; and vaginal intercourse while she is menstruating or in postpartum bleeding, as this is forbidden. Anything else regarding her body is permissible at all times, even if it leads to ejaculation by her hand or any part of her body. The wife is not permitted to refuse her husband's request for intimacy, always, provided it is not anal intercourse, and not vaginal intercourse during menstruation or postpartum bleeding. The Prophet, peace and blessings be upon him, commanded the wife to come to her husband even if she was on the oven. And the Prophet, peace and blessings be upon him, used to fondle his wives while they were menstruating, without intercourse.
