* Kindly refer to Mas'alah No. 329: https://www.sistani.org/english/book/48/2159/
329. Wudhu becomes void on account of the following seven things:
Passing of urine. Excretion. Passing wind from the rear. A sleep, deep enough to restrict sight and hearing. However, if the eyes do not see anything, but the ears can hear, Wudhu does not become void. Things on account of which a person loses his sensibility, like insanity, intoxication or unconsciousness. Istihaza which will be dealt with later. Janabat, and, as a recommended precaution, every state which requires Ghusl.
