Is it permissible to caress and kiss one's wife until semen is released without penetration, or must semen always be released inside the vagina, except in the case of a wet dream?

A man is permitted to enjoy his wife in every way, except for anal intercourse or vaginal intercourse while she is menstruating or in postpartum bleeding (nifas). It is commendable to caress and kiss the wife and to provide everything that helps her achieve orgasm, thereby fulfilling her desire. There is no blame on a man if he ejaculates outside the vagina, whether he was overcome or did so by choice, but in this case, the wife's permission is required.
