Assalamu alaykum
wot does one do if he forgets that he is chewing gum and starts his salaah?
does it break his salaah?
if not, should he finish his salaah?
or
Break it himself and dispose of the chewing gum

Also
if one has to break salaah for a valid reason , how does one break the salaah?
should he do salaam to both sides in whichever posture he is and break his salaah? If not, how do you do it.

Jazakallah
