The Ruling on the Invalidity of Wudu Due to Fainting

Question:
Or, my brother, this is a person whom Allah has granted understanding, and he said what he said in the first instance.

Answer:
If a person loses consciousness due to fainting, yes, his wudu is invalidated, because if it is invalidated by sleep, it is also invalidated by fainting. If he faints or takes some medication 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 what comes out of him afterward; the state of ritual impurity occurs and he is unaware of it. 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. Therefore, if his consciousness is lost through sleep, fainting, or anesthesia, his wudu is invalidated.
