Q: My question is about part of the satr becoming exposed during salaah. If someone performs salaah in a t-shirt and his satr becomes exposed whilst going into ruku or sajda, does this have any effect on the salaah?
A: If the satr is exposed during the salaah for the duration of three subhaanallahs, the salaah will be invalid.
And Allah Ta’ala (الله تعالى) knows best.
