A doctor touching a patient's private parts, whether front or back, invalidates the ablution

Q: What is your opinion, Your Eminence, regarding the fact that a doctor's work sometimes requires seeing or touching a patient's private parts for examination? And sometimes, during surgeries, the surgeon works in an environment filled with blood and urine. Is it obligatory to renew the ablution in these cases? Or is it merely a matter of preference?

A: There is no harm in a doctor touching a man's private parts out of necessity and looking at them for treatment, whether the private part is the back or the front. He is permitted to look and touch out of necessity and dire necessity. There is no harm in touching blood if there is a need to touch it in a wound to remove it or to know the condition of the wound, and he washes his hand afterwards from what has affected it. The ablution is not invalidated by touching blood or urine, but if he touches the private part, his ablution is invalidated, whether it is the front or the back.
As for touching blood or urine or other impurities, the ablution is not invalidated, but he washes what has affected him. However, if one touches the private part without a barrier, meaning touching flesh with flesh, his ablution is invalidated; due to the saying of the Prophet (peace and blessings be upon him): And likewise, if a female doctor touches a woman's private part out of necessity, her ablution is invalidated by that if she was in a state of purity, just as with a man.
