What is the ruling on a woman making up missed prayers after undergoing surgery, when she was unconscious or in pain, and should she make them up all at once, even if she is unsure of their exact number? And what is the ruling on combining and shortening prayers in the hospital?

The woman's action of abandoning prayers due to exposure to doctors is wrong, and she must make up the prayers she missed, as well as the prayers she missed due to fainting. Making them up is more prudent. As for her prayers with tayammum and qasr, if she was unable to perform wudu or did not intend to stay for four days or more, then her prayers are valid; otherwise, she must repeat them. She must enumerate the prayers that need to be made up and make them up according to her ability.
