Q: I would like to know if someone sleeps whilst sitting on a chair or car seat or aero plane seat, will his wudhu break?
A: If it is a very light sleep where he has control over himself, wudhu will not break. Where it is a deep sleep he should renew his wudhu.
And Allah Ta’ala (الله تعالى) knows best.
