Is it obligatory for the doctor or the patient to perform ablution (wudu) or make up for the fast (qada' as-siyam) after a vaginal examination?

Mere looking does not invalidate ablution (wudu') or fasting for either the female doctor or the patient. Touching with a barrier does not nullify ablution, but touching without a barrier nullifies the ablution of the one who touches, according to many scholars, and this is the relied-upon and authoritative opinion (mufta bihi). A vaginal examination does not invalidate the fasting of the female doctor. As for the patient's fasting, the authoritative opinion (mufta bihi) according to us is that it is not invalidated.
