Rule : Whilst in the middle of performing Wuzu it breaks then perform the Wuzu again, and if the water that is held in the palm of the hand and you release wind then this water is useless and do not use it to wash any parts.
Damnit i was just about finished , and i farted , ill have to start again.. grr
Rule : If sperm was ejaculated from it's place but not due to lust, i.e. it was done by lifting a heavy load or falling from a height, then to bathe is not obligatory, however, the Wuzu is broken.
AHA that must be where the saying " i knocked the sperm right out of you " came from
Rule : If semen dropped but was very thin and it came out whilst urinating or on it's own accord without lust then the bath does not become necessary but the Wuzu will break.
Smokeys rule, never pee in your bath
