What is the ruling on cosmetic treatment for a facial disfigurement by a doctor suspected of being Israeli? And what is the ruling on refusing the father's request and making him angry in this regard? And is the questioner sinful for not searching for another doctor?

If the doctor who will perform the surgery is trustworthy and more skilled than others in his field, he should be given precedence, even if he is a disbeliever (kafir). Ibn Hajar al-Haytami said: "The most skilled doctor is to be given precedence over others, even if he is of a different race or religion." Al-Shabramallasi mentioned that this includes giving precedence to a disbeliever if he is more knowledgeable than a Muslim. Therefore, the questioner must obey her father in having the surgery performed by this doctor if he insists on it for her treatment. This is further emphasized by the fact that most scholars believe it is obligatory to obey one's father in matters of doubt.
