If you don't know you passed gas etc. does your salat count? If you don't know a thing breaks wudu and you've done before must you make up your prayers? Are we counted for what we don't know?

In principle, a person shall be considered in the state of Wudhu until he
has full conviction that this Wudhu did not break. (al-Ashbah)

Nabi (Sallallaahu Alayhi Wasallam) said, 'If a person is confused to whether
his Wudhu broke or not, then he should leave the Musjid until he is sure
that his Wudhu broke.' (Mishkaat pg.40; Qadeemi)

and Allah Ta'ala Knows Best
