How does one pray who enters the operating room before the midday prayer

Question : A woman wants to enter the operating room, as she is ill, before the midday prayer, and the operation may last a long time. How does she pray the midday and afternoon prayers?

Answer : I say that if this woman who wants to enter the operation knows that she will not regain consciousness until after the sun has set, then it is obligatory for her to ask the doctors to postpone the operation until the sun has set, meaning until the time for the midday prayer has entered, and then she prays the midday and afternoon prayers combined. Then the operation is performed. Because it is not permissible to delay the prayer from its time. And in my opinion, the doctors will agree to this. As for if it is more likely in her opinion that she will regain consciousness before the time for the afternoon prayer ends, then there is no harm in her entering the operation. Then, if it happens that she does not regain consciousness until after the sun has set, there is no sin on her, but she makes up the midday and afternoon prayers.
