Q. Is a Salaat valid (if performed in its correct timing) had the Adhaan been called before its correct timing?
A. Once the Salaah has been performed on its correct time (that is, when the permissible time for Salaah has entered) then the Salaah will be valid, even if the Adhaan was called before the correct time.
And Allah knows best.
