What Invalidates Wudhu.
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; Istibra - which will be dealt with later; every
state which requires Ghusl, like Janabat.
