Is drinking alcohol one of the things that nullify ablution, and can its ruling be analogized to that of sleep in nullifying ablution?
The loss of sanity due to consuming intoxicants invalidates ablution (wudu') by the agreement of the people of knowledge, and this is more profound in removing the intellect than sleep. Ablution is invalidated by insanity, unconsciousness, and intoxication by consensus, with no difference between a little or a lot of it. As for sleep, there is a difference of opinion regarding it, but the majority of the people of knowledge consider it to be an invalidator of ablution.
