Q. Does it invalidate the fast if somebody kisses his wife?
A. ??? ??? ??????? ??? ??? ??? ???? ?????? ???????? ? ????? ??? ?? ???? (bahrur ra iq 6:191)

Kissing in itself does not break the fast. One must make sure that there is no exchange of saliva, taste, etc. that exists as a result of such a kiss.

It is best that one refrains from doing things during their fast that could lead to adult related actives. These adult related activities could result in not just the invalidation of a given fast, but make kaffarah necessary. Kaffarah requires a person to fast 60 fasts consecutively.

Allah (SWT) knows Best
