The invalidation of wudu' by the return of consciousness from fainting or anesthesia

Question:
And regarding the matter: Is it obligatory to choose what the colors and waking up are, whether the duration is long or short?

Answer:
If a person's consciousness returns from fainting, no, his wudu' is not invalidated. Because if it is invalidated by sleep, it is also invalidated by fainting. If he faints or takes something, takes something from the medicines that covers his perception, such as anesthesia for example, then his wudu' is invalidated due to the loss of his consciousness. So he does not know after that what comes out of him; the state of ritual impurity comes out of him and he does not know. Because as long as a person is awake and has his consciousness, he controls himself. But if his consciousness is lost, he does not control himself. So if his consciousness is lost by sleep, or by fainting, or by anesthesia, then his wudu' is invalidated. Yes.
